R7 price 259,800, pure electric world challenger officially launched

　　On September 24th, at Huawei’s autumn full-scene new product launch conference, Hongmeng Zhixing’s first coupe SUV Zhijie R7 was officially launched, and the new car price was 259,800 yuan – 339,800 yuan. Zhijie R7 shows super product power through excellent appearance design, large space, long battery life and many Huawei black technologies, and is expected to become the next popular model of Hongmeng Zhixing.

　　In appearance, the Smart R7 adopts the body design of a coupe SUV, and the rear of the car is raised, allowing the rear passengers to have more head space, taking into account the appearance and practicality. In terms of details, the new car follows Huawei’s design principle of "extreme, simple and pure". The star track fusion light group on the front face plus the external active air intake grille, and the 3D energy crystal penetrating light at the tail, which is full of movement. At the same time, the smooth body lines, combined with the hidden door handle and blackened sports tail wing design, make the new car have an ultra-low drag coefficient of 0.219Cd.

　　Intelligent experience has always been the advantage of Hongmeng Zhixing products, and Zhijie R7 is no exception. First of all, on the smart drive, the vehicle will be fully equipped with the HUAWEI ADS 3.0 high-end intelligent driving system. We have already had a preliminary understanding of the strength of this system on the Enjoy S9. The application of the new end-to-end architecture not only allows the vehicle to significantly improve in NCA smart driving, active safety, automatic parking, etc., but also allows the vehicle to have the ability to cover the whole scene. From the Enjoy S9, we can also see that the current Huawei smart drive has been able to achieve autonomous driving capabilities from parking spaces to parking spaces, and the decision-making is also more anthropomorphic, bringing the experience of using the smart drive system to a new level.

　　In addition, the new car is also equipped with Hongmeng Cockpit 4.0, which has a rich application ecosystem far exceeding that of the same class of models. At the same time, the Smart R7 also supports HUAWEI MagLink multi-terminal interconnection, and the big model blesses smarter Xiaoyi, making the cockpit interaction more anthropomorphic. In terms of cockpit space, the rear legroom in the car reaches 956mm, and the head space reaches 1034mm, bidding farewell to the cramped and crowded SUV of the coupe. The rear also supports 27 ° -37 ° stepless electric adjustment and ventilation, heating and massage functions. 3.8L & 3.5L double storage drawers are also set under the seats, which is very convenient.

　　It is worth mentioning that the Zhijie R7 is the first SUV model of Hongmeng Zhixing to be equipped with a co-pilot zero-gravity seat. The zero-gravity seat has 18-way seat adjustment and leg support heating, and supports continued reclining to 137 °, allowing passengers to lie down completely. At the same time, thanks to the large rear space, when the co-pilot zero-gravity seat is opened, the rear seat still has a good space performance.

　　In addition to the smart driver and the smart cabin, the "full blood" Tuling platform is also the highlight of the Smart World R7. The new car is equipped with active intelligent curve control, intelligent downhill cruise, and active anti-skid control functions, which have strong capabilities in three aspects: easy driving, safety, and comfort. In terms of hardware, the new car adopts front double fork arms + rear five-link independent suspension, and the whole system is equipped with continuous variable damping shock absorber and air suspension as standard. With the support of air suspension, the maximum height adjustment range of the Smart World R7 body is plus or minus 50mm, which can maintain good passability while improving vehicle vibration avoidance performance. From the previously released closed-beta video, it can be seen that the Smart R7 has shown an outstanding performance in the face of various light off-road scenarios such as continuous steep slopes, deep pit steep slopes, pebble roads, twisted roads, and shell craters.

　　In terms of battery life, the intelligent R7 will be equipped with Huawei’s new DriveOne 800V silicon carbide high voltage platform and Huawei’s giant whale 800V high voltage battery platform, with a maximum battery life of 802km, charging for 15 minutes can supplement 400 kilometers of battery life, and then cooperate with the national 80,000 + cooperative charging network, which can completely eliminate consumers’ battery life and energy anxiety.

　　Looking back at the first half of this year, Hongmeng Zhixing’s success is obvious to all, especially in the field of SUVs. The Q M7 and Q M9 have become the benchmark products in their respective price points. The Q R7 is also on the trend of becoming a hit, and it has won more than 30,000 orders in a small order time of two weeks. We have reason to believe that the new car will become a strong competitor of Model Y with the product advantage of the vehicle itself, reshaping the competition landscape of 25-350,000 pure electric SUVs.

Hengda Automobile Hengchi 5 starts pre-sale, and the ＂notarized＂ reservation method creates a precedent

(Wen/Pan Yuchen, editor/Lou Bing) On July 6, Hengda Automobile’s first mass-produced model, Hengchi 5, which was mired in the whirlpool of public opinion and repeatedly bounced tickets, finally started pre-sale, and launched a model. After comprehensive subsidies, the pre-sale price is 179,000 yuan, which will be delivered in October this year.

Hengda President Liu Yongzhuo said at the press conference that the Hengchi 5 is "the best pure electric SUV in history within 300,000 yuan", and will achieve 10,000 deliveries by Quarter 1 next year.

The Hengchi 5 is positioned as a medium-sized SUV, with a body length, width and height of 4725/1925/1676mm and a wheelbase of 2780mm. The exterior design combines elements such as a suspended roof, a guide tail, and a hidden door handle to enhance the stylish and sporty feel of the vehicle.

Inside, the central control of Hengchi 5 is equipped with a wrapping 3D curved triple screen, composed of 10.25-inch instrument panel, 14.6-inch central control screen and 10.25-inch co-pilot screen, built-in Qualcomm 8155 chip, support mobile APP unlocking, facial recognition, 5G network, multi-application synchronization display, Baidu AI voice, gesture operation and other car-machine interaction functions.

The Hengchi 5 is equipped with five millimeter-wave radars, 12 ultrasonic radars, one monocular camera, and four surround-view cameras. It is claimed to be equipped with more than L2-level auxiliary driving, and integrates 19 auxiliary driving capabilities including full-speed adaptive cruise, automatic lane change, and automatic parking.

In terms of power, Hengchi 5 is built on a pure electric platform, using Bosch UMC three-in-one electric drive, with a maximum power of 150kW, a maximum torque of 345Nm, 0-100km/h acceleration of 7.8s. The chassis uses a suspension combination of front McPherson and rear multi-link, and the braking distance of 100-0km/h is 34.5m. Powered by Ningde Times CTP lithium iron phosphate battery, the rated power is 72.8kWh, and the CLTC cruising range reaches 602km.

In order to attract consumers to buy, Hengchi 5 also launched the first 10,000 car users to reduce 10,000 yuan, return and refund within 15 days of picking up the car, and buy back at a 40% discount for three years after picking up the car. It is worth mentioning that Evergrande Auto promises that the pre-sale deposit and final payment will be paid to a special account established by a notary office in Tianjin, in the name of ensuring the safety of consumer funds.

Hengda Motor said that it will use the direct sales and authorized sales agent model to set up Hengchi showrooms and agent stores in major cities such as Beijing, Shanghai, Guangzhou and Tianjin. This year, the number of stores will reach 200, and 313 after-sales services outlets will be deployed in 235 cities across the country. In terms of charging services, Hengchi APP is connected to 563 domestic charging service providers, covering more than 300 cities in 31 provinces.

For new car-making forces, boasting Haikou at the new car launch is a "basic operation". Compared with Li Xiang’s "best within 5 million yuan" and Yu Chengdong’s "beyond a million luxury cars", Liu Yongzhuo’s expression of "the best pure electric SUV within 300,000 yuan" is quite reserved.

Objectively speaking, the price of Hengchi 5 combined with its product power is quite reliable. The main competitors of Hengchi 5 are concentrated in the price range of 150,000-250,000 yuan, including Volkswagen ID4, GAC Aian V, Xiaopeng G3, Nezha U, Zero Run C11 and many other pure electric SUV models. In terms of configuration level and system parameters alone, Hengchi 5 does have a good price/performance ratio compared with competing products. In addition, a series of operations such as 10,000 yuan for the top 10,000 car users, refund within 15 days, 30% off repurchase in three years, and collection by the notary office are also extremely rare in the history of car sales.

It can be seen that in order to dispel consumers’ car purchase doubts, Hengda Automobile can be said to be heartbroken. But as Murphy’s Law indicates, the biggest test of Hengchi 5’s market prospects is not the product itself, but more from off-site factors.

From Xu Jiayin’s bold words "buy buy buy, big big, good", to Hengda’s release of 6 new cars in one breath, to the market value once exceeded 600 billion, and then to the outside world’s doubts about its PPT car manufacturing and pre-sale repeated delays, Hengda Automobile has gone through two and a half years so far.

With the overall explosion of Hengda Group, the credibility of this new cross-border car manufacturing force has actually dropped to freezing point. In May this year, there were even rumors that Hengda Automobile would delay sales indefinitely. Although Hengda has come forward to refute the rumor on the grounds of the epidemic, it is still difficult to dispel the public’s doubts.

Today’s Hengda car is like the child who kept shouting "wolf is coming". After all, in the heyday of Hengda Real Estate, its football, property insurance, grain and oil, ice spring and other side businesses, which one was not prosperous, and now which one is not a chicken feather? Compared with these, the auto industry is a bottomless pit that burns money. As an outsider, Hengda wants to achieve "the best within 300,000 yuan" in the short term, and the difficulty is comparable to the sky. Moreover, even if Hengchi 5 does sell well in the end, it is difficult to obtain enough bicycle profits based on its current pricing. This also means that it is difficult for Hengda to block the hole of real estate thunder by selling cars in the short term. After the announcement of the pre-sale of Hengchi 5, the market reaction was still rather lukewarm. If Hengda wants to truly turn around, the order performance before delivery will be crucial.

Happy 37th Teachers’ Day! Andy Lau and Donnie Yen are teachers like this

1905 movie network feature On September 10, 2021, we ushered in the 37th Teachers’ Day. For thousands of years, countless writers and writers have written classic masterpieces praising teachers; in recent decades, a group of filmmakers have also created vivid and lively teacher images on the big screen with light and shadow.　

For example, the sunny and cheerful physical education teacher in "Close to Your Heart", the "domineering" teacher who seems to be old-fashioned and impersonal in China, but is actually serious and responsible, and the stern head teacher who says nothing and is full of majesty in China are all remarkable images of screen teachers on the big screen.　

Teachers are always a beam of light that illuminates the future of students. Teachers need to remember, and teachers’ kindness should be remembered. On the annual Teachers’ Day, we might as well look at the faces of educators on the big screen while remembering our youth and thanking teachers’ kindness!

01

At the 22nd Chinese Film Golden Rooster Awards, a film that focuses on the selfless dedication of teachers in mountainous areas swept four awards: Best Feature Film, Best Director, Best Actress and Best Supporting Actress.　　

Zhang Meili (played) is a typical rural woman. After the loss of her husband and children, she devoted all her energy to the children in the village. Before the arrival of the volunteer teacher, she was the only teacher in the village school.

Although her cultural level is not high, she always treats every student with sincerity and enthusiasm, insisting on teaching them every bit of what she has learned.

In order to provide her children with a better learning environment, she sacrificed her dignity and sought funding. For the sake of the children’s long-term teachers, she resolutely gave up staying in Beijing and chose to return to the village to teach.

Zhang Meili’s interpretation is the perseverance, sincerity and simplicity of teachers in mountainous areas.　

As a rural teacher, the volunteer teacher she plays is another kind of portrayal. She is from Beijing, can play the piano, can recite, is knowledgeable, and is generous. When she first arrived at the Loess Plateau, she had the idea of leaving because she was not comfortable with the soil, but when she really wanted to leave, she was hesitant to leave because of her students.

The volunteer teacher who once chose to bid farewell to rural teaching did not hesitate to return to this dusty land after Zhang Meili passed away unexpectedly, and consciously shouldered the heavy responsibility of disseminating knowledge to children.

The life of the rural teacher subtly changed the trajectory of her life, and she was enthusiastic and open-minded, and eventually became Zhang Meili’s "successor" to pass on the spark.　

In the touching scene of the film, Zhang Meili said to the students affectionately, "People can be poor, but their ambitions cannot be short. Everyone must study hard, walk out of this mountain, get into a good university, and come back to build their hometown, so that they don’t have to eat potatoes every day, and they don’t have to be looked down upon by others…" The tearful admonition is her education to reverse the fate of her child’s life, and it also symbolizes the infinite expectations of a rural teacher for children.　

Mention the impressive village teacher on screen, as well as the old professor played in "The Last Lesson."

The professor who was far away in a foreign country suffered from dementia due to a cerebral infarction, but the memory still stuck in his mind was the experience of teaching at Wangxi Village Primary School decades ago. Therefore, a group of grown-up students did their best to restore the changed classroom to its original state, hoping to return to the past with the teacher.　

The prototype of Fan Wei’s character is Fang Pinger, a rural teacher who has been rooted in mountainous areas for nearly 40 years. In the play, the students go to great lengths to create artificial rain, the professor leaves in a small boat, and the students stand on the bridge to say goodbye, all based on the real experience of Fang teacher.

Mr. Fang often says, "I can’t let go of the children in the village, especially the left-behind children." This reflects Fan Wei’s role in the play, even when he retires, he never really let go of his thoughts about the students.　

Due to the lack of educational resources for children in mountainous areas and the relatively backward educational facilities, the role of rural teachers is self-evident; while urban children are well-off, their growing pains are also entangled in them, and the teacher’s mission to lead students astray is also not light.

　In the movie, Chen Xia, who plays the role, becomes a "spicy teacher". Because his students are brave and aggressive, addicted to games, or unable to focus, all of them are poor in their studies, which makes Chen Xia have to compete with this group of naughty teenagers. He even "fights" on campus and adopts extraordinary "alternative teaching".

Fortunately, Chen Xia’s "teaching" gradually worked. He resolved the knot in the students’ hearts, led them out of the vicious circle of "depravity", and finally won the applause and respect of the whole class.

In its bones, "Big Brother" tells the story of a teacher who protects his students and never gives up on every child. Similarly, there are some similarities.

In the movie, the music teacher played by Yan Zilang has to lead a group of useless students who are forced to participate in the "Blood Choir Experimental Project" due to trouble to complete a self-challenge.

In the face of a group of children who are tone-deaf and have no intention of learning, Mr. Yan can be said to have used 18 kinds of martial arts, such as walking blindfolded, playing with two people and three legs, or trying hard to persuade students to learn. He is enthusiastic about leading students to experience the frustration and joy of growth and encouraging them to move forward bravely.　

The images of teachers on the screen were always different. Whether they were rural teachers, urban teachers, strict teachers, or loving teachers, their teaching intentions and teaching styles were different, but it was certain that they could always bring new hope to students and water their growth with love.

02

Every teacher’s teaching career has endless happiness and bitterness, and every actor who creates the "screen teacher", while pouring effort into the role, can also deeply feel the difficulty of educators.　

Because of the distance between real life and the state of the character, Ni Ping is very stressed to play "Zhang Meili" bluntly. To this end, she has visited many primary schools to observe the little bits and pieces of rural teachers, and started by changing the voice and appearance to be as close to the character as possible.

Nearly 70 days of shooting time, almost all of which are five in the morning and ten in the evening, she shared, "This is the norm for rural teachers."

Fan Wei also confessed in "The Last Lesson" that in order to present the true state of old age, he has to wear makeup for two hours a day. During the shooting process, he can experience the difficulties of the teacher’s profession firsthand. "I especially admire rural teachers!"

"There are a lot of action scenes in this movie, including racing, blasting, and fighting, but the teacher’s setting makes it impossible for me to use weapons, so I can only use local materials, such as using stationery such as chalk to’partner ‘, which is quite difficult."

In addition, in order to play a better role as a music teacher, Andy Lau not only specifically followed the Hong Kong Children’s Choir to experience life, but also consulted professional conductors for conductor details and skillfully integrated them into the role creation.　

It is worth noting that the image of screen teachers in recent years seems to be more profound. Whether it is Chen Xia played by Donnie Yen or Yan Zilang played by Andy Lau, their past hides an unknown side.

The former was a special forces soldier who had experienced the pain of war, and he was also a troubled teenager in his youth. He had always felt extremely guilty for "breaking" his classmates’ piano dreams with his own hands. The latter was bright and advocated that there should be no class, but he also escaped drunk driving due to poor teaching results.

It can be said that as teachers, they are completing their own salvation while teaching their students.　

Regarding the expansion of the image of teachers in the film, Zhang Ningjuan, a domestic teaching researcher, concluded that "Chinese teachers on the screen" generally present a professional image that treats students with care, regards them as their own, treats teaching seriously and responsibly, is dedicated to work, and is much loved and respected.

However, with the surging of various social contradictions, the image of teachers on the screen has gradually changed from the original high-ranking to the present, paying more attention to communication and dialogue with students, and incorporating more social reality and personal emotional life into the image connotation. In other words, in future movies, the image of teachers may usher in richer connotations with social changes.


In any case, screen teachers are just a microcosm of thousands of educators. For this group of lovely people, what we should do is to transform knowledge into nourishment for life, learn to be grateful, and learn to contribute, in order to repay the teachers for their earnest teachings and their half-life dedication on the three-foot podium.

Beidou-3 Final Star was successfully launched! The meeting point reveals the way forward for Beidou

　　Intersection news, with the successful launch of the Beidou-3 GEO-3 satellite, our country’s Beidou satellite navigation system construction project has been successfully completed, the star array has been listed, and the global "Skynet" has been successfully woven. What changes will the "Beidou-3" bring to our lives in the future? After more than 30 years of practice and exploration, why is our country so persistent in the construction of the "Beidou" system? The reporter interviewed Professor Wen Xin and Professor Kang Guohua from the School of Aeronautics and Astronautics of Nanjing University of Aeronautics and Astronautics to explore the way forward for Beidou together.

　　You’ve already used Beidou, but you may not know it.

　　Many people know that our country launched the Beidou satellite, but they do not know that Beidou has long been available to the people and open to the world.

　　If you pay attention, it is not difficult to find that your smartphone can always accurately tell the time, almost not like a watch, occasionally "going fast" or "going slow", and it is the Beidou satellite navigation system that helps you "check the watch".

　　Kang Guohua, a professor at the School of Astronautics at Nanjing University of Aeronautics and Astronautics, told reporters that "Beidou" is not just a satellite launched into the sky, but a huge system project. Seemingly out of reach, it is actually closely related to our lives. "Since the 1980s, the whole world has been using the GPS of the United States. With the Beidou system, the absolute dominance of GPS in the field of global satellite positioning has been challenged, and now most of our mobile phones have begun to use the Beidou navigation system."

　　He took out his mobile phone and showed the reporter the satellite zenith map displayed by the mobile APP. The picture shows the movement of the satellites of the four major satellite navigation systems in the world on the local zenith. They are the Global Navigation and Positioning System (GPS) of the United States, the GLONASS system of Russia, the Galileo system of the European Union, and the Beidou system of China. "Among them, the color satellites that can receive signals are in orbit, while the black and white ones are temporarily unable to receive signals."

　　Each Beidou satellite weighs 850KG, has a payload weight of 300Kg, and carries three functions – positioning, timing and short message. Positioning is the foundation of navigation, and navigation is the application of positioning, Kang Guohua said. Positioning is "telling you where you are" and navigation is "telling you how to go from where you are now to where you want to go."

　　Timing, as the name implies, is to "give the exact time". For some instruments and equipment, it is to calibrate the time. As long as the Beidou timing function is used, even if it is distributed in different parts of the world, the time can still be "synchronized". Kang Guohua told reporters that time synchronization is a national security guarantee, such as high-speed rail, power grid, computer network communication, etc., all need time synchronization. For example, relying on the precise positioning of Beidou, the high-speed rail brakes from 350 kilometers per hour to parking, and the final stop error can be controlled within 10 centimeters.

　　Short messages are a unique feature of China’s Beidou. Unlike GPS receivers, which can only receive satellite signals in one direction, Beidou receivers can not only achieve positioning, but also send and receive text messages similar to mobile phones, and transmit two-way text messages through satellites.

　　During the Wenchuan earthquake rescue in 2008, the ground communication facilities were seriously damaged and even paralyzed. The rescue troops used Beidou short messages to send the first message from the disaster area, accurately reporting the disaster situation and the location of the disaster to the disaster relief and rescue headquarters, which played a huge role. At that time, the accuracy of "Beidou No. 1" was actually not high enough. Its two-way communication function had shown great power and saved countless lives.

　　"The stars move", and a "Skynet" has been woven for more than 20 years.

　　Behind the dream of "Big Dipper" is the relay struggle of several generations, from nothing to something, from weak to strong, the "Big Dipper" star is increasingly dazzling.

　　Professor Wen Xin of the School of Aeronautics and Astronautics of Nanjing University of Aeronautics and Astronautics told reporters that people’s ideas about the Beidou satellite navigation system can be traced back to 1983. Academician Chen Fangyun, a famous aerospace expert, first proposed the concept and idea of dual satellite positioning.

　　"The chief designer who set a three-step development plan for the Beidou satellite navigation system is Sun Jiadong, the father of our country’s’two bombs and one star ‘." Wen Xin introduced that in 1994 our country launched the construction of the Beidou satellite navigation test system, which is the "Beidou generation". The second step was to start the construction of the Beidou satellite navigation system in 2004. In 2012, a regional passive service capacity was formed. And the third step was this year, the formation of a global passive service capacity. "From 2007 to 2010, a network of satellites was launched continuously, weaving an information network in the sky."

　　Since the "Beidou Generation" uses a dual-star positioning method, the "Beidou Generation" has a lot of room for improvement in positioning accuracy, timing accuracy, service area, etc., especially the problem of large signal transmission delay. "For example, the positioning accuracy of the" Beidou Generation "is 20 meters, which means that the" Beidou Generation "cannot" see "two objects less than 20 meters away from the distant space and calculate their position difference.

　　Kang Guohua said that at present, our mobile phones are generally integrated with satellite systems from two, three or even four countries. "Why don’t we use China’s Beidou system alone? Because the Beidou-2 system focuses on the Asia-Pacific region, the service in other parts of the world is not very stable."

　　Kang Guohua compared the multiple launches of Beidou satellites to "puzzles". Beidou-1 is an experimental satellite, with only four satellites, which are only over our country and have all been decommissioned. Later, Beidou-2 is a regional networking satellite, covering a total of 20 satellites in the Asia-Pacific region. The space segment of the "Beidou-3" satellite navigation system consists of 27 medium-earth orbit satellites, 5 synchronous orbit satellites, and 3 inclined synchronous orbit satellites, totaling 35 satellites.

　　From the first satellite of Beidou-2, our country has launched 54 Beidou navigation satellites, which have been officially put into the network since June. The last network satellite launched on June 23 is the 55th in the entire Beidou satellite navigation system.

　　Kang Guohua said that although this time we launched the last star in the puzzle, in fact, the satellites in the Beidou system have been changing. "Each satellite has a lifespan, and it needs to be retired in an average of 8-10 years. Since the construction of the third generation of Beidou, many satellites have been retired and added. The significance of the 55th star is to make the Beidou system truly the Beidou of the world, and it can be located anywhere on earth."

　　The brightest Chinese star, let the stars in the sky "refer to the Big Dipper"

　　What is the significance of the Chinese astronauts’ dedication to the "Beidou" satellite?

　　As an important weapon of the country, Beidou is a major space infrastructure in our country. The goal of building our country’s space-time reference network and navigation information network is an important support for my great power status and strategic interests. "It can be said that the sooner the construction is made, the more strategic advantage it will have." Kang Guohua gave an example. "Satellite positioning requires the transmission of radio waves at specific frequency points from the sky to the ground. Since only specific frequency points have the least attenuation during the process of electromagnetic waves penetrating the atmosphere, these frequency points have become important strategic resources." According to the current ITU’s "first-served" rule for frequency point allocation, the United States has chosen the best frequency band because it was the first to build GPS.

　　The competition in satellite navigation is not only the competition of the technical system, but also the competition of constellations and signals. China, Europe, and the United States have gone through years of coordination work on satellite frequency and orbital position issues, and even "open and secret wars", which are full of "games" of aerospace powers.

　　The Beidou-2 navigation system has experienced such a pressing time. According to the relevant regulations of the ITU, the Beidou-2 navigation system must complete the satellite navigation signal in orbit and broadcast to the ground within seven years. Otherwise, the priority right to use the navigation frequency will be cancelled. It is necessary to reapply for the frequency and carry out relevant international coordination. As a result, our country will lose the best opportunity to develop a global satellite navigation system.

　　Facing the urgent development task, Chen Zhonggui, an alumnus of Nanjing University of Aeronautics and Astronautics and then the deputy chief designer of the Beidou-2 satellite, led the party commando team to improve the integrated test verification method, and fought for 8 months with "5 + 2" a week and "white + black" every day. On April 16, 2007, two days after the successful launch, Beijing received a clear signal from the flight test satellite. At this time, there were less than 4 hours left before the space frequency failure – it was this feat that effectively protected the frequency resources of our country’s satellite navigation system and opened the prelude to the construction of the Beidou regional navigation system.

　　"Today, the successful networking of the Beidou-3 global satellite navigation system marks that our country has the" capital "of PK with the strength of the US GPS navigation system in the field of satellite navigation systems. Beidou is not only a national project, but also a national project. ‘Beidou’ has multiple’firsts’." Wen Xin listed that the Beidou satellite navigation system has adopted the hybrid constellation system of three orbits (GEO, IGSO, MEO) for the first time; it has reached the requirement of 100% localization of components for the first time; and it has proposed cooperation and compatibility for the first time… These all make China’s aerospace and satellite monitoring technology more confident in the world.

　　For example, the on-board atomic clock, which is the "heart" of a navigation satellite, was once a technological blank in China. There was a time difference between radio wave transmission and reception, and the time difference multiplied by the speed of light was the distance. As long as the error was one second, the distance would be 300,000 kilometers. During the development of Beidou-2, a Swiss company was introduced, but later the European Union required the company to provide atomic clocks that were an order of magnitude less accurate than the "Galileo" navigation system, which made Chen Zhonggui and the design team more deeply realize that "key core technologies cannot be bought, or they cannot be bought, or they cannot be bought."

　　Today, our country has conquered the key technologies of rubidium atomic clock and hydrogen atomic clock, and used these two atomic clocks on the Beidou navigation satellite to achieve the establishment of time benchmarks. Among them, the on-board rubidium atomic clock has achieved 100% localization of components, and the current accuracy can reach 3 million The error is only 1 second, and the passive on-board hydrogen atomic clock has an error of 1 second in 10 million years.

　　At present, the Beidou-3 satellite has formed a distinct Beidou feature in terms of positioning services, wide-area enhancement services, global short message services, search and rescue services, etc., and has achieved partial leadership in foreign technology in terms of system signal performance, system transmission and ranging performance, on-board atomic clock performance, and localization of key products and components. In the open class on ideological and political affairs of Nanjing University of Aeronautics and Astronautics, Chen Zhonggui confidently pointed out that "the core of the Beidou-3 system is to serve the world with higher accuracy and higher performance," so that China’s Beidou is also the world’s Beidou! "

　　The era of "Beidou +" has begun, and it must be easy to use both in the sky and on the ground

　　After the Beidou global network, the speed of integrating the Beidou system with positioning, timing and short message services into the lives of ordinary people will accelerate. "Beidou +" life will come faster.

　　"It will become an infrastructure like the water grid and the power grid, and daily life can no longer be separated from it. If you order a takeaway or order a ride-hailing car, you need to use satellite positioning to determine your current location." Kang Guohua said, but then Beidou has to solve various problems such as reliability, accuracy and stability.

　　"Beidou’s biggest problem now is application promotion." Kang Guohua said that after all, GPS has been developed more than 20 years earlier than us, and users have become sticky and inertial. Take mobile phones as an example, replacing GPS chips with Beidou chips will increase a lot of external costs, and merchants have no incentive to replace them. Therefore, in some mature areas of GPS applications, replacing Beidou often encounters relatively large resistance. But the more people use Beidou, the lower the cost will be, and the faster the iterative improvement speed will be, forming positive feedback.

　　The research on "low-orbit satellite navigation enhancement" currently led by Professor Kang Guohua is related to the promotion and application of Beidou. "If we compare the Beidou system to a highway-like backbone network, it can provide positioning accuracy better than 10 meters; then our work is similar to building’provincial roads’, and further improve the accuracy on the basis of this backbone network."

　　As an example, Kang Guohua said that when you shuttle between city buildings, due to the "canyon" effect formed by the buildings, you can see the sky is very small, so the signal received by the satellite is small and weak. The low-orbit navigation enhancement system is to add another layer of low-orbit constellation below the Beidou constellation, and use the navigation enhancement system on the low-orbit satellite to achieve Beidou signal enhancement and broadcasting, thereby improving the strength of the signal and upgrading the original Beidou road-level positioning to lane-level positioning. Before we could know where people were, now I have to know whether you took your left foot or your right foot. "Kang Guohua said. Now Japan has a Quasi-Zenith satellite that does something similar, but they do it with GPS, and our team did it with our own Beidou.

　　In the future, the Beidou satellite navigation system will have a wide range of applications in land, sea, aerospace, mass consumption and other fields. "For example, in marine fisheries, the navigation of ships and the establishment of an integrated fishery information service network are inseparable from the positioning signal of the Beidou system." Wen Xin said that in the field of transportation, the application of advanced satellite navigation technology is an important means to realize the informatization and modernization of transportation, and is of great significance to the establishment of a smooth, efficient, safe and green modern transportation system. "

　　The reporter learned that the Beidou system has begun to be applied in many fields in our country. For example, the hydrological monitoring system based on the Beidou system has realized the real-time transmission of hydrological and water regime information, greatly improving the accuracy of rain, water regime, drought and disaster information collection and the timeliness of transmission. It has been widely used in southern Shaanxi, the Yangtze River Basin and the Yellow River Basin in our country, and the number of users has reached more than 4,000. "In the field of weather forecasting, after many years of meteorological digital message transmission application experiments, a series of meteorological forecast-type Beidou end point equipment and system application solutions developed by scientific researchers have solved the automatic transmission and collection of weather station digital messages and the visual display function of weather station map distribution by the National Meteorological Administration and meteorological centers in various cities. At present, the end point of Beidou application in the meteorological field has reached thousands of units. "

　　Microlink – "Beidou No. 3" Chief Engineer "Nanhangzao"

　　"Beidou-3" also has a cordial connection with Jiangsu. Its chief designer, Chen Zhonggui, is an 86-level alumnus of Nanjing University of Aeronautics and Astronautics.

　　"Look up at the starry sky, hold up the ambition to explore the universe. Work hard to realize the dream of a space power." On this year’s fifth "China Space Day" and the 50th anniversary of the successful launch of the "Dongfanghong No. 1" satellite, Chen Zhonggui sent an affectionate message to the students of his alma mater.

　　Chen Zhonggui has worked in the Aerospace Academy for 31 years after graduation, of which 20 years have been engaged in work related to Beidou. Beidou satellite navigation system has grown from nothing, from weak to strong, from regional to global, he has witnessed 80,000 Beidou people working day and night, painstaking research and dedication.

　　In December 2018, Chen Zhonggui returned to the campus of China Southern Airlines and brought a shocking open class on the ideology and politics of the alumni chief teacher "Beidou Navigation Satellite" to the students. Chen Zhonggui, who originally studied mining machinery as an undergraduate, quit his job after working for a few years out of yearning for his aerospace dream and chose to apply for the mathematical mechanics major of Nanjing Institute of Aeronautics and Astronautics (the predecessor of Nanjing University of Aeronautics and Astronautics), under the tutelage of Professor Zhu Ming, who is engaged in multi-body dynamics research.

　　"The study style of China Southern Airlines is very strict, especially the requirements of the professional basic courses are particularly high, and the exams are not ambiguous." This is what Chen Zhonggui remembered most when he was studying in graduate school. He still remembers the automatic control of this course, "The exam results are not satisfactory, and the teacher will talk to the students to help the students analyze the reasons, and draw inferences from one another." It is with such a rigorous study style and dedicated professional teachers that Chen Zhonggui made up for the gap in professional foundation in time during his graduate school, laying the foundation for the later work development.

　　Under the guidance of Mr. Zhu Ming, Chen Zhonggui aimed his graduate thesis at the new modeling theory of multi-body dynamics and the development of analytical software. During the writing of his graduate thesis, he had more opportunities to come into contact with the field of aerospace, and at that time, aerospace was most lacking in professionals engaged in basic disciplines such as dynamics and heat. It was this opportunity that Chen Zhonggui "naturally" formed a tacit connection with aerospace, and after graduation, he resolutely chose the Fifth Academy of Aerospace, a field he had pursued and loved.

　　In the open class for the students of China Southern Airlines, Chen Zhonggui comprehensively reviewed the development process of our country’s Beidou satellite navigation from No. 1 to No. 3, and systematically described the technical evolution and major innovation achievements of our country in the field of satellite navigation systems. Now the Beidou satellite navigation system has achieved 100% localization of stand-alone products that make up satellites, and all core components have been localized. It has become the fourth mature satellite navigation system after the US GPS, the Russian GLONASS system, and the European Galileo system.

　　Compared with Beidou-2, Beidou-3 requires more complete functions, more indicators, and higher reliability. How to achieve a leap in system performance in a short period of time is a severe challenge for the Beidou-3 demonstration team. Chen Zhonggui led the development team to check the data, build the standard, build the model, make the layout, and compile the plan, and finally formed a technical demonstration report that meets the different needs of all parties.

　　Looking to the future, he hopes to build a Beidou satellite navigation system that serves the world, is focused, distinctive, locally leading, and has a smooth transition, forming a more ubiquitous, more integrated, and more intelligent benchmark space-time system. Making China’s Beidou also the Beidou of the world is his unswerving career goal for satellite navigation, and it is also a solemn oath to our country’s aerospace power.

Volvo cars have a new LOGO!

What do you think of Volvo’s new LOGO?

Article Source: LOGO Master ID: Logods Image Source: Volvo official, Weibo (invasion and deletion) Author: Da Jun Editor: Ai Sheng

Early this morning.

Da Dajun received the explosion information from fans.

Volvo cars have changed their LOGO!

what？ Volvo, this is not about putting

Replace the classic ring LOGO …

As we all know, Volvo’s original LOGO

Its outer frame is in the shape of a ring with an arrow.

It has the meaning of a wheel, with a diagonal across it in the middle.

Make the whole more "stable"

And the text part is highlighted with white characters on a blue background.

It is also the symbol registered by VOLVO company.

It’s in ancient Egyptian font

You can see that the original LOGO

It presents a three-dimensional effect by adding shadows and metallic textures.

And the new LOGO becomes flat and flat!

The new LOGO removes the metallic texture.

And diagonal elements in the middle.

The combination of circle and arrow is kept in a flat form.

And the word "VOLVO"

Where the circle and the arrow in the upper right corner

Designed by the original closed form

The space is processed.

And the design of words

The previous serif fonts are used.

Only the distance between letters has been adjusted.

Make it look more "loose"

Speaking of which, let Dajun think

Another Volvo logo

We’re behind the Volvo car

And you can see it on the website.

The word "long distance"

So

The routine for Volvo to change the logo is

Keep the font and distance?

On the whole, the new LOGO is designed in a minimalist style.

Become younger, more modern and have affinity.

At present, the new LOGO of flat wind

It has been used in various channels.

Official website page

official microblog

And on the APP icon

In addition, in Volvo this June,

Launch a new pure electric concept car

You can also see the use of the new LOGO.

For the release of Volvo’s new LOGO,

Undoubtedly caused a heated discussion among netizens.

Some people think that flat design conforms to the trend.

But the new LOGO has a thinner ring.

It makes people feel uncomfortable

Some fans also said that

Still prefer the original LOGO.

There are even people who "digress"

Driving in the comments section?

(imagine for yourself)

However, this flattening operation

Some people also think of the public before.

The new LOGO is also flattened.

Speaking of which, the operation of Volvo’s new LOGO

Flatten+remove text bottom frame

It also reminds Dajun of Nissan, which released a new LOGO last year.

This routine, is it the same!

Put the new LOGO of the two brands together

Is there a feeling of "two brothers"

In fact, from the perspective of the global automobile industry,

Starting from the MINI owned by BMW in 14 years,

The trend of flattening of automobile brand LOGO

It got out of hand.

Audi

Changan automobile

This is because many automobile brands are carrying out electric innovation.

Competing to launch and improve the product line of electric vehicle series

The minimalist and flat LOGO can better show the sense of science and technology that enterprises need.

In addition, it is probably influenced by the current information age.

Nowadays, electronic screen is the main information carrier.

Therefore, the minimalist style of "less is more" simplifies and centralizes the content.

On the one hand, this will make the brand better publicized.

On the other hand, it also gives designers more room to play and imagine.

So, in the automotive industry,

Who will join the flattening team next?

In the face of the ＂cliff-like＂ decline in the price of centralized mining, how to deal with the heart stent enterprises？

Sheng: the "past lives" of heart stent

Cardiac stent, also known as coronary stent, is a high-value consumable commonly used in percutaneous coronary intervention (PCI), which has the function of dredging arterial blood vessels and is recognized as a conventional treatment for cardiovascular diseases. Since the first generation of stents went on the market in 1997, the development of cardiac stents has gone through three stages, the first generation is the balloon expansion era, the second generation is the bare metal stent era, the third era is the drug-eluting stent era, and it is now moving towards the fourth generation of completely degradable stents. With the continuous evolution of materials, the performance is more and more optimized. The main features of each generation of cardiac stents are as follows:

Fig. 1 development of cardiac stent

At present, non-degradable drug eluting stent,DES) is still the mainstream choice for clinical application, and fully degradable stent is still in the early stage of product development and clinical application. At present, the mainstream cardiac stents in the market are still drug-eluting stents, and the market share has remained at around 99% since 2012, and balloons and bare metal stents have been completely replaced by them. Biodegradable stents (BRS) can be gradually absorbed in the body, which can significantly reduce the formation of stent thrombosis and restenosis, at the same time, it will not affect MRI and CT scanning, and also facilitate the re-intervention process. It is the main direction of stent research and development in the world, and has attracted extensive attention from medical device companies at home and abroad. At present, the fully degradable heart stents put into research and development are mainly divided into two categories: degradable metal materials and degradable polymer materials.

Fig. 2 Types of mainstream cardiac stents currently in use

(A) In recent years, the demand for cardiac stents has been increasing, and the scale has steadily increased.

1. The number of PCI interventions in China ranks first in the world, and the number of PCI interventions has increased by over 15% annually in recent five years.

From 2015 to 2019, the number of cases of percutaneous coronary intervention (PCI) in China increased steadily, with an average annual increase of 16.0%. Among them, the number of percutaneous coronary intervention (PCI) in China in 2019 was 1.03 million, ranking first in the world, with an increase of 12.6% compared with 2018. It is conservatively estimated that there will be nearly 1.2 million cases of percutaneous coronary intervention (PCI) in China in 2020.

Fig. 3 Trends of PCI operation volume in China from 2015 to 2020 (data source: analysis by Health Research Institute).

In 2020, the market value of heart stents in China is close to 17.5 billion yuan.

From 2015 to 2019, the number of cardiac stents implanted in China showed a steady growth trend year by year, with an annual growth rate of 15%-20%. In 2019, the number of cardiac stents implanted in China was 1.6 million. In terms of market value, the market value of heart stents in China increased from 9.75 billion yuan to 15.97 billion yuan from 2015 to 2019, with an average annual growth rate of 15.2%. It is estimated that the market value will be close to 17.5 billion yuan in 2020.

Fig. 4 Trend chart of cardiac stent implantation quantity and scale in China from 2015 to 2020 (data source: analysis by Health Research Institute).

(B) The "market just needs+policy orientation+technology promotion" troika escorts the rapid development of the cardiac stent industry.

1. The market just needs:The two major trends of younger coronary heart disease and aging population have once again "expanded" the cardiac stent market.

Younger coronary heart disease:Cardiovascular disease has become the number one health killer in the world, accounting for nearly 30% of the total global deaths. According to China Cardiovascular Health and Disease Report 2019, the number of cardiovascular patients in China reached 330 million, accounting for more than 45% of the deaths of residents, ranking first among all diseases. Among them, the number of patients with coronary heart disease has reached 11 million, with more than 3 million new patients each year and more than 1 million patients with sudden infarction. In addition, the younger trend of coronary heart disease (CHD) is increasing. According to a survey of cardiovascular diseases among more than 20,000 people in Shanghai, the number of patients with CHD accounts for nearly 30%, of which 27.0% are over 70 years old, 40.0% are 51-70 years old, and 33.0% are under 50 years old. CHD is no longer a "patent" for the elderly, and it is obese, stressful and stressful.

Figure 5 Proportion of cardiovascular disease population structure (data source: public information)

Aging:According to statistics, in 2019, the population aged 65 and above accounted for 12.6% in China. From the development trend, the population aging speed and scale in China are unprecedented. After 2022, China will enter a deeply aging society with a proportion of over 14.0%, a super aging society with a proportion of over 20.0% around 2033, and then it will continue to rise to 35.0% in 2060. The arrival of the era of deep aging will undoubtedly raise the "ceiling" of the heart stent industry.

Figure 6 Structural trend of population aging in China (data source: public information)

With the development of younger coronary heart disease and aging population, and considering the impact of centralized procurement on the price of cardiac stents and the improvement of people’s health awareness, the number of PCI operations per capita in China will be in line with that of developed countries in the future (the number of PCI operations per million population in China is 736, that in the United States is about 3,135, and that in Japan is about 2,047, which is 4.3 times and 2.8 times that in China, respectively). According to the extreme analogy method (referring to the number of PCI operations per million people in Japan, mainly considering that China and Japan are similar in race and incidence), it is estimated that the peak number of PCI operations will reach 2.87 million in the future. Considering the average number of stents implanted in PCI (about 1.5 stents/case), the corresponding peak number of cardiac stents implanted is about 4.3 million, which has a large long-term permeability and market space.

Fig. 7 Comparison of the number of percutaneous coronary intervention (PCI) between China and major developed countries (data source: analysis by Health Research Institute).

2. Policy orientation:Front-end encouraging innovation and end-collection specification help the market demand of cardiac stents to be released continuously.

In recent years, the state has launched a series of favorable policies for the medical device industry to support the rapid development of enterprises:

innovateEncourage the acceleration of the transformation and upgrading of medical devices, develop high-end interventional products such as fully degradable vascular stents, and stimulate the development of new cardiac stents market segments; Priority is given to the review and approval of qualified innovative medical devices. Under the promotion of innovation policy, the fully degradable polymer matrix drug (rapamycin) eluting stent system (NeoVas) independently developed by Lepu Medical and the fully degradable polylactic acid stent (Xinsorb) independently developed by Academician Ge Junbo of China Academy of Sciences have all entered the special approval procedures for innovative medical devices.

circulateFrom the national level to the provinces and cities, the centralized purchasing scheme of high-value consumables has been launched one after another, constantly rationalizing the price system of high-value medical consumables and improving the supervision and management of the whole process. In October 2020, coronary stents became the first batch of purchased varieties, and the national level started the collection of high-value medical consumables.

Table 1: Main policies related to high-value consumables such as cardiac stents from 2016 to present:

3. Technology promotion:The iterative upgrading of products and the improvement of interventional surgery level greatly enhance patients’ confidence and willingness to receive interventional therapy.

Iterative upgrade of products: cardiac stent has experienced the development from balloon expansion to drug-eluting stent, and the restenosis rate of stent implantation has decreased by nearly 20%, and the incidence of thrombosis in stent has decreased to about 1%, which effectively reduces the risk of complications for patients;

Improving the level of interventional surgery: China has successively established the training base of cardiovascular interventional diagnosis and treatment of the Ministry of Health and the national quality control center of PCI, and adopted a unified training model to carry out systematic training nationwide, and issued certificates after passing the examination, and carried out quality control and index monitoring on related work. In 2018, the mortality rate of interventional therapy for patients with coronary heart disease was 0.26%, far lower than that in the United States.

(III) Competition pattern: Domestic substitution in the cardiac stent industry has basically been completed.

After decades of development, the technical generation gap among major enterprises has gradually narrowed, and the industry pattern has been basically stable, mainly relying on the launch of new products to enhance market share. Judging from the competition pattern, the concentration of cardiac stent industry is high, and the market share of domestic drug stent products exceeds 70%, and the domestic substitution is basically completed. Among them, domestic brands such as Weichuang, Lepu and Jiwei rank among the top three, with a total market share of over 65%.

Figure 8 Market share of domestic cardiac stent brands in 2019 (data source: analysis by Health Research Institute)

In 2019, the revenues of cardiac stents (including balloons, catheters and other ancillary products) of minimally invasive medical care, Lepu medical care and Jiwei medical care were 1.83 billion yuan, 1.79 billion yuan and 1.74 billion yuan respectively, with growth rates of 33.0%, 26.7% and 24.9% respectively. As can be seen from the figure, cardiac stents of minimally invasive medical care showed a trend of "double high" in sales growth rate and market share.

Figure 9 Market share and revenue growth rate of cardiac stent head enterprises (data source: analysis by Health Research Institute)

Change: the national "group purchase" triggered a major change in the heart stent industry.

With the landing of the national heart stent collection, the "suicide" price reduction of enterprises has also brought infinite reverie to the future direction of the industry. Will the heart stent industry under centralized procurement be a "broken wrist" or a "rescue" in the future? Is it "price for quantity" or "innovation and transformation"?

(A) the change in scale

Centralized procurement of cardiac stents directly affects the purchase price. According to the recent centralized purchasing list published by the Medical Insurance Bureau, the number of intentional purchases in the first year exceeded 1.07 million, involving 27 products. Based on the published average price quoted by the winning bidder (1682 yuan/piece) and the amount of coronary stents implanted in 2021, the market value in 2021 is about 3.19 billion yuan. It should be emphasized that the market value forecast here does not consider the impact of the decline in centralized purchasing price on the improvement of patients’ willingness to operate.

Fig. 10 Market value forecast of cardiac stent in 2021 (data source: analysis by Health Research Institute)

According to the previous estimation of the amount of cardiac stent implantation in China, when the amount of PCI operation per 100 people reaches the Japanese level, the peak amount of cardiac stent implantation in China is 1400 x 2047 x 1.5 = 4.3 million. According to the heart stent of 1682 yuan/piece (the average price of centralized procurement), the corresponding market value of heart stent is 7.23 billion yuan:

Fig. 11 Market value of China cardiac stent corresponding to peak value (data source: analysis by Health Research Institute)

From the above analysis, it can be seen that under the influence of centralized procurement policy, the market value of heart stents in China in the next 1-3 years is expected to be in the range of 3-7 billion yuan.

How much money can patients save after centralized collection?

As we all know, the "floor price" of centralized purchasing has a great influence on patients who are unwilling to undergo interventional surgery because of the high price. This paper analyzes the payment situation of patients before and after centralized purchasing (according to the conventional reimbursement policy):

Fig. 12 Comparison of patients’ self-funded amount before and after centralized purchasing (data source: analysis by Health Research Institute)

As can be seen from the above figure, according to the same reimbursement policy, the out-of-pocket medical expenses of patients decreased from 6520 yuan to 308 yuan before and after centralized purchasing, and the personal burden was only 4.7% of the original, which greatly eased the economic burden.

(2) Changes in business

In addition to the industry scale being affected, the business tentacles of heart stent enterprises will also be adjusted:

1. Stent market: form a low-cost medical insurance centralized procurement market+off-standard non-medical insurance high-end alloy stents+medical insurance stainless steel stents+non-medical insurance ultra-high-end degradable stents.

In the short term, the market of cardiac stent products will form a pattern of low-cost medical insurance centralized procurement market+off-standard non-medical insurance high-end alloy stent+medical insurance stainless steel stent+non-medical insurance ultra-high-end degradable stent:

On the one hand, from the current attitude of centralized mining, bare metal stents are not included in the list of centralized mining, and the price of stainless steel stents will be under pressure due to the price reduction of centralized mining in the short term, and the price inversion with alloy stents will not last long; In the long run, stainless steel stents are not as good as alloy stents in terms of support and passability. As a more backward technology than Co-Cr alloy and Pt-Cr alloy, stainless steel stents will face marginalization in the future. However, in view of the fact that the use of stainless steel coronary stents still accounts for about 40% of the market share in 2019, stainless steel coronary stents will be coasting for a period of time in the future.

On the other hand, with the continuous promotion of cardiac stent collection, the trend of differentiation and stratification of end patients will become more obvious, and the group of self-paid high-priced stents may expand. Degradable stents and metal stents belong to two price bands, so it is impossible to talk about the market share substitution after the huge change of centralized purchasing price. Moreover, the proportion of consumables in the cost of PCI surgery has further decreased, and the audience’s marginal willingness to pay for innovative products is likely to increase. In the medium term, the development rhythm of fully degradable stents will continue to be stable, in order to get as much clinical data as possible, enhance the recognition and acceptance of products by more experts, doctors and patients, and enhance the high-end market share.

Figure 13 Future product layout of cardiac stent

2. Business reshaping: cultivate and expand new medical formats around the cardiovascular field, and make a forward-looking and diversified layout.

On the one hand, it conforms to the latest concept of "intervention without implantation" of the current interventional instruments, and extends upstream and downstream around the coronary intervention chain:

Product chain: the price reduction of metal stents will be the norm in the future, and the fully degradable stents and drug balloons with "intervention without implantation" will become the core of future development. Facing the policy impact of centralized stent mining, it will be an effective hedging means to extend the layout of coronary intervention chain. In addition to completely degradable stents, a new generation of drug-coated balloon (DCB) has also become the core of future development under the new concept of "interventional non-implantation". The data shows that the usage of drug-coated balloons in some hospitals or individuals in Europe has reached 50%-90% of all PCI, and Japan has reached 4,000 per month, accounting for about 15% of Japanese PCI. In addition, auxiliary consumables (balloons, catheters, guide wires, etc.) related to coronary intervention will also become the profit growth point that enterprises pay attention to.

Technical service chain: The further decline in the proportion of consumables in the cost of PCI surgery has prompted enterprises to speed up the layout of medical services and health management sectors. Conditional enterprises will cooperate with primary hospitals to provide equipment consumables, drugs and medical technical services needed for interventional diagnosis and treatment, and promote the grassroots promotion and popularization of new interventional technologies, which will become an important exploration for coronary intervention enterprises to face the centralized procurement of high-value consumables.

On the other hand, the centralized procurement of cardiac stents has prompted enterprises to expand from coronary intervention to peripheral intervention, and continuously enrich their product lines:

Make full use of enterprise stent balloon design and precision manufacturing platform technology, constantly innovate and develop, expand the company’s products from coronary intervention to peripheral intervention, continuously enrich the cardiovascular disease product line, and concentrate on improving the company’s marketing network structure to cope with market risks brought about by policy uncertainty.

Figure 14 Possible business development direction of cardiac stent enterprises under the background of centralized procurement

(C) changes in the market

Under the general trend and background of medical insurance fee control and national centralized procurement, it has a great influence on the competition pattern of domestic medical industry. Medical device enterprises will face more fierce market competition, as well as the realistic problems of product prices and product profit margins falling sharply. For the leading enterprises in the industry, although they can seize more market share by winning the bid at a low price, the problem of shrinking scale and declining profit rate cannot be underestimated.

In the foreseeable future, the scope of domestic medical insurance control fees will only increase, so as to more effectively reduce the pressure of medical insurance expenditure, reduce the prices of drugs and devices and benefit the people’s livelihood. In addition, the situation in the field of devices may appear in the previous pharmaceutical field, and importers may take more aggressive quotations to seize the domestic market after they are familiar with the rules.

For domestic cardiac stent enterprises, facing the policy risks of centralized procurement and medical insurance control, they need to seize the domestic share, turn their attention to the international market and participate in the international market competition. In fact, domestic heart stent head enterprises have also started the international strategic layout, among which minimally invasive medical care, Lepu medical care and Lan Fan medical care are typical representatives.

Turn: Transforming into a strategic choice for heart stent enterprises to overtake in corners.

In the face of major changes in the national medical device policy, cardiac stent enterprises actively predict the development trend, plan ahead, and focus on developing products and new businesses related to centralized procurement while strengthening product technology innovation. For domestic heart stent enterprises, what transformation layouts have been made at present? What is the possible key direction of development in the future?

(1) Adjust the business strategic map and form a multi-sector support system.

1. Diversification of business lines-minimally invasive medical treatment

Through business diversification, we will continuously broaden profit points and enhance comprehensive competitiveness. In recent years, Minimally Invasive Medical Devices Co., Ltd. (hereinafter referred to as "Minimally Invasive Medical") has continuously enriched its product line and expanded its business field through outreach acquisition and endogenous development. Products gradually changed from early cardiovascular stents to diversified business systems covering cardiovascular intervention, orthopedic medical devices, heart rate management (pacemaker), arterial and peripheral vascular intervention, and nerve intervention products.

In 2019, the business revenue was 5.55 billion yuan, of which 33.4% came from cardiovascular interventional products, 29.3% from orthopedic medical devices, 26.3% from heart rhythm management business, 6.1% from arterial and peripheral vascular interventional products, and 3.5% from neurological interventional products. In 2012, the revenue of minimally invasive medical cardiovascular interventional products (stents) accounted for 83.8%.

Figure 15 Comparison of the proportion of minimally invasive medical business segments in 2012 and 2019 (data source: minimally invasive medical annual report)

2. Product line "from one to four", and build a platform business model of "equipment+medicine+medical service+new medical care"-Lepu Medical.

Lepu (Beijing) Medical Devices Co., Ltd. (hereinafter referred to as "Lepu Medical"), as one of the earlier enterprises engaged in the research and development of cardiovascular interventional medical devices in China, has been accelerating the business integration, optimization and layout in recent years, and has developed from a single stent business in 2013 to four business segments covering "devices+drugs+medical services+new medical care" at present, with the goal of building a platform-based business model around the whole life cycle service for cardiovascular patients.

Figure 16 Main contents of each business segment of Lepu Medical

Dual track of medical devices and medicines: In terms of revenue, the revenue of Lepu Medical in 2019 was 7.80 billion yuan, a year-on-year increase of 22.6%. Among them, the medical device sector achieved operating income of 3.62 billion yuan, accounting for 46.4%, and the pharmaceutical sector achieved revenue of 38.5%, accounting for 49.4%. Among them, the revenue of coronary stent system only accounts for 20% of the total revenue of Lepu Medical. In addition, the market share of the company will be directly increased after winning the bid, and the negative impact of centralized procurement is relatively limited.

Figure 17 Revenue Ratio of Lepu Medical in 2019 (Source: Lepu Medical Annual Report)

3. "Health protection+medical equipment" two-wheel drive-Lan Fan Medical

Lan Fan Medical Co., Ltd. (hereinafter referred to as "Lan Fan Medical") is a leading enterprise in the field of medical gloves in the world, accounting for 22% of the global market. In 2018, it successfully acquired the fourth-ranked cardiac stent company in the world, Singapore Baisheng International Group, and realized its layout in the field of medical devices. Subsequently, Lan Fan Medical implemented the "A+X" industrial strategy, and set up four business divisions with a total of seven tracks:

Figure 18 Layout of Lan Fan Medical Industry

At present, Lan Fan Medical has two business series products, namely health protective gloves and heart stents, which are continuously extended to the whole chain of emergency care, cardiovascular and cerebrovascular diseases, forming a multi-business sector collaborative model combining low-value, medium-value and high-value consumables products, with complementary modes and risk hedging. In 2019, Lan Fan Medical achieved a revenue of 3.48 billion yuan, of which the revenue of health protective gloves was 1.68 billion yuan, accounting for 48.3%, and the revenue of cardiac interventional devices (including self-produced and agents) was 1.74 billion yuan, accounting for 50.0%.

Figure 19 Revenue Ratio of Lan Fan Medical in 2019 (Source: Lan Fan Medical Annual Report)

(2) Expand the cardiovascular product chain and form a diversified ecological closed loop.

1. Strategic positioning of big heart-minimally invasive medical treatment

Based on its own existing technology and platform, minimally invasive medical care constantly lays out big heart tracks: coronary heart disease, arrhythmia, structural heart disease and heart failure.

Development contextMinimally invasive medical care started from coronary stent, then cut into radiofrequency ablation, and then extended to pacemaker business. Later, with the further development of interventional technology, structural heart disease entered the era of minimally invasive surgery, and minimally invasive medical care opened up the technical path of completing heart valve replacement by interventional method (representative product VitaFlow transcatheter aortic valve system). Compared with these business units with mature products, Minimally Invasive has begun to "plan the layout" of the treatment solution for heart failure, which is also an important pawn for the future layout of Minimally Invasive and the key to completing the closed loop of the big heart business.

2. Optimize iterative coronary medical devices, enrich and innovate the implantable product line-Lepu Medical.

Lepu Medical has built a rich product group of devices in the cardiovascular field:

1) Accelerate the industrial chain matching of coronary intervention devices. In 2019, Lepu medical coronary stent products achieved operating income of 1.53 billion yuan, a year-on-year increase of 23.3%; Supporting auxiliary consumables (balloon catheter, guide wire, etc.) realized an operating income of 260 million yuan, up 51.0% year-on-year. Under the background that most of the auxiliary PCI interventional materials such as balloon catheter guide wire are monopolized by foreign capital, Lepu Medical is the only R&D and manufacturing enterprise in China that can provide all the consumables for coronary intervention. At present, more than ten necessary consumables such as pre-expanded and post-expanded balloon catheter, PTCA guide wire, guide catheter, contrast guide wire, contrast catheter, sheath, Y valve, triple tee, pressure extension tube, pressure pump, ring handle syringe, pressure sensor and hemostasis compressor have all been mass-produced.

2) Coronary balloon products and NeoVas bioabsorbable stents are expected to form new growth points. In February 2019, NeoVas, an international second-generation bioabsorbable drug stent independently developed by Lepu Medical, was approved for listing in China, and opened a new era of PCI technology "intervention without implantation". In July 2019, the first-generation coronary balloon was approved by GMP for the first time. Three products of the second-generation drug balloon series are about to start clinical trials, and the third-generation rapamycin drug balloon technology has made breakthrough progress, and animal experiments will be carried out soon.

In addition, in recent years, Lepu has actively developed peripheral products of degradable and drug balloons based on the Group’s coronary stent and balloon platform technology, and its business scope has expanded from coronary intervention to peripheral intervention.

3. Layout of coronary artery, valve, nerve intervention and peripheral intervention-Lan Fan Medical.

At the time when the medical device industry entered the golden period of development, Lan Fan Medical continuously accelerated the overall layout of cardiovascular and cerebrovascular devices based on the leading edge of Baisheng International Cardiology Department:

In the field of coronary intervention: all kinds of stent products produced by Singapore Baisheng International are sold to more than 90 countries and regions around the world, with a sales volume of 400,000. At present, BioFreedom, a drug-coated stent of BA9? without polymer carrier, has been introduced into European and Japanese markets, and it is expected to be listed in the United States and China in the near future. From the perspective of stent technology, the upgrading of technology is still the theme of stent industry and the driving force of sales growth. The increase in the proportion of high-end stents such as BioFreedom and Excrossal, as well as the development of foreign markets, have helped to enter the new product bonus period. In addition, taking the cardiac stent as the fulcrum, we will enrich, expand and improve the product line combination related to PCI surgery, such as contrast guide wire, contrast catheter, guide wire, guide catheter, pre-expanded balloon, post-expanded balloon, puncture needle, arterial sheath and pressure extension tube.

Cardiovascular related product lines: Apart from coronary artery, valve, nerve intervention and peripheral intervention are also the tracks that Lan Fan Medical keeps cutting in. By continuously expanding and expanding related product lines such as valve, nerve intervention, peripheral intervention and drug balloon, the competitiveness of product portfolio will be enhanced. The capital is undoubtedly the quickest way for Lan Fan Medical to broaden the track. In June, 2020, Lan Fan Medical acquired the fifth manufacturer of TAVR in the European market. NVT’s main business is the research and development, production and sales of interventional valves for structural heart disease. Through the acquisition of TAVR, a gold track for medical devices, NVT officially entered the field of minimally invasive interventional structural heart disease therapy with broad prospects.

(C) the implementation of internationalization strategy to enhance the international market share of products.

1. Actively deploy the global mainstream market-minimally invasive medical care.

Since 2014, minimally invasive medical care has set its sights on overseas and accelerated the export of China native coronary stents to overseas markets. In 2019, the overseas business of minimally invasive medical drug-eluting stents achieved revenue of 160 million yuan, a year-on-year increase of 72.4%. Sales in 25 countries or regions and registration certificates in 13 countries or regions. Among them, Firebird2TM’s overseas revenue increased by 186.9% year-on-year, FirehawkTM’s revenue increased by 54.6% year-on-year, and it has been sold in several major European countries. In addition, the group has also submitted the application for registration of FirehawkTM stent to the Japanese medical device review and approval authority, and actively deployed the global mainstream market.

2. Establish an international business department to increase the market share of international innovative products-Lepu Medical.

Lepu Medical put internationalization on the agenda after the first round of domestic drug collection in 2018, and proposed to further increase the market share of international innovative products. At present, the original foreign trade business and departments of all subsidiaries have been integrated, and the international business department has been established to strengthen the international influence on the upstream and downstream of the medical industry chain in the cardiovascular field. Explore the possibility of setting up R&D centers and production bases overseas. Overseas R&D centers have been planned to accelerate the clinical registration of innovative products (degradable stents, TAVR3.0, renal artery ablation, artificial intelligence ECG and artificial intelligence monitoring) in the world.

It is reported that Lepu Medical’s business revenue from abroad in the first half of 2020 was 870 million yuan, an increase of 320 million yuan compared with the whole year of 2019. Guo Tongjun, senior deputy general manager and secretary of the board of directors of Lepu Medical, said at the reception of listed companies that the company’s overseas market target remains unchanged, and the proportion of overseas market revenue will continue to increase to 20%-30% in the next 3-5 years.

summarize

National centralized procurement is not only a reshuffle of the cardiac stent industry, but also an impetus to the cardiovascular segmentation field. Heart stent enterprises still have a long way to go, but whether they are facing the "change" of the industry calmly or actively responding to the "turn" of the industry, there are undoubtedly two ways to go: First, strengthen the technological innovation and product iteration of heart stents in order to obtain new user markets; The second is to realize business diversification and risk hedging with the heart stent as the fulcrum.

Play the villain and then the policeman! After Under the Sun, Peng Guanying took on a new play. Do you think it will be a play？

In Under the Sun, Feng Xiaosheng finally won a short victory, forcing Liang Yuze to go abroad and live a self-righteous and beautiful life with Ke Ying. Even, Ke Ying invited Feng Xiaosheng to have dinner together, and their relationship made progress in stages.

Ke Ying fed Feng Xiaosheng steak, and then withdrew it when he was about to get into the mouth. Feng Xiaosheng forcibly took her arm and ate the steak. The expression of the two people’s confrontation exposed the man’s possessiveness completely.

This flowing expressive force is attributed to the actor’s acting skills: I just saw A Ying’s surprise when she was feeding, and the meat was slowly handed to her mouth to show a spoiled smile. Ke Ying took back her hand and suddenly froze, and then she was fierce and overbearing when she grabbed her hand and ate it. There was nothing wrong with Peng Guanying. Taking this drama is undoubtedly the most correct choice he has made.

"Under the Sun" has aroused a thousand waves since it first announced that the novel was made into a film and television. For no other reason, the original novel "Things in the Palm" describes that the university lecturer He Yan still tries to get rid of the clutches after being imprisoned by the male host Fu Shenxing. In order to highlight the tense relationship between men and women, there are many explicit and cruel pictures. However, it is definitely impossible to film and television all the contents, so everyone’s attitude towards TV dramas is both tense and contradictory.

Sure enough, after the TV series was broadcast, a lot of content was added and deleted in order to be more practical, and even the male master was changed into a male two. But what hasn’t changed is that the role played by Peng Guanying is still an object of resentment.

But Peng Guanying’s acting didn’t disappoint everyone. Whether it is Shen Shijie’s diabolical cruelty in the early stage or the cruel cunning of Feng Xiao’s voice in the later stage, Peng Guanying interprets it perfectly and impeccably.

Theoretically speaking, Peng Guanying is a newcomer to film and television, but unfortunately he is a newcomer of great age.

Before, everyone could only think of Princess Lanling, which co-starred with Baby Zhang a few years ago. Although his acting skills were also praised in the play, there was no follow-up resources, and he seemed to disappear from the audience’s field of vision soon.

After that, when I think of him, I can only remember that he and Zhu Yilong, who have exploded in recent years, are close friends, and Peng Meimei and Zhu Meili are active in each other’s social platforms.

However, with the online drama "The Soul of the Town", Zhu Yilong made numerous rounds, followed by other works, and soon gained a firm foothold. And "Peng Beauty" is still an invisible man.

In 2020, Zhu Yilong and Liu Shishi’s new drama "Dear Yourself" landed in iQiyi, in which Peng Guanying played love rat, who betrayed his wife. After a long time, Peng Guanying’s acting remained at a certain level, and playing against Adi often made people hate it. I wish he would disappear immediately.

Later, when he lost his way and asked his wife to forgive him, his eyes were tearful, and the audience shouted, so pitiful that I even wanted to forgive him.

Peng Guanying finally became famous.

With the update of "Under the Sun" episode by episode, Feng Xiaosheng’s temperament is also slowly changing, from revenge on Ke Ying at the beginning to hopelessly falling in love with her later, all of which are manifested in the actor’s smiles, which also tests the actor’s acting skills.

But Peng Guanying has performed well from the beginning, and he is bound to play the role well from beginning to end.

Years ago, Peng Guanying’s new play "Backlight Man" started, with Zhang Yujian as his partner, both of whom played the role of police.

The online drama "Backlight" is adapted from the novel "In the Dark" by writer Jin Shichai, which mainly tells the story of undercover policeman Xie Lanshan and portrait expert Shen Liufei fighting criminals together.

Xie Lanshan, played by Peng Guanying, and Shen Liufei, played by Zhang Yujian, met at the police academy. They established a strong affection and vowed to become excellent anti-drug policemen.

Among the posters issued at present, this group of quasi-anti-drug policemen are determined, and they are willing to hide in the dark to protect the light.

Perhaps the audience is still immersed in the vicious villain in Under the Sun, but Peng Guanying has turned over and become a policeman. With his acting skills, he is bound to perform a completely different image from Feng Xiaosheng and look forward to his new works. Wen/Hua Su

Burst! Get married early for playing ball! This is the role model of the players!

We’ve seen many ways to take a break in the NBA over the years.

In order not to play ball, various operations are endless.

Of course, if it is expanded to the level of the national team,

The reasons are even more strange, and reasonable ones include:

The previous season was too tired and needed time to rest.

Of course, it also includes the life event of "getting married"

"No, do you mean me?"

Some people cringe, others walk with their heads held high.

At the beginning of recruiting players for the World Cup, the United States team

Big names are refusing, so that the stars are dim.

People say that the dream team is not as good as Canada next door.

However, brunson announced his joining early.

He was the first to sign up and also the first to report.

It is also the first batch to invest in training camps.

What’s more, in order to concentrate on the national team competition,

Don’t let your personal life affect the whole.

He was originally scheduled to marry his fiancee on September 2.

Shengsheng finished the wedding one month in advance!

He also invited university teammates and national team teammates to witness together.

After the teammates witnessed it, the bottle was thrown and the suit was taken off.

Go directly to the national team training camp without neglect.

No honeymoon! I just want to play basketball!

People say: Life is bigger than basketball. Come to him

Everything is just a derivative of basketball.

At the end of the season, everyone else was busy on vacation.

Brunson has begun to complain that the season hasn’t started yet.

He can’t wait to hit another level.

All kinds of wild game bureaus and training bureaus in the middle have not fallen behind.

Although we stand in brunson’s wife’s point of view.

The husband is eager to serve the country and is absorbed in his work.

It must have affected the sweetness of the couple’s daily life.

But if you look at it from the perspective of the American men’s basketball team.

In the absence of big names, there is such a person.

So focused, so crazy, so serious

Others will be infected more or less, so strengthen your enthusiasm.

But then again, this year’s US team lineup

It is indeed the most embarrassing dream team in the past years.

Do you think the American team can make it into the top four this time?

If the NBA is a cup, who do you think is the champion?
The new activity of NBA hero opens! The last day of today

Manchester city wants to win the championship？ The Premier League champion is overwhelming.

Manchester City beat Real Madrid 5-1 in UEFA Champions League (UCL) this season and entered the final.

After the 2020-21 season, Manchester City entered the Champions League final again after two years. At that time, due to the 0-1 loss to Chelsea, the champion suffered setbacks, but finally got revenge.

Whether Manchester City can win UCL, Premier League (EPL) and FA Cup at the same time has attracted much attention.

The competition of EPL championship made Arsenal feel a favorable atmosphere. He hasn’t reached the top of the league since the 2003/04 season.

However, in the case of Arsenal’s decline, Manchester City launched a fierce pursuit. If one more champion is added, the EPL championship trophy will be won.

Manchester City also reached the final in the FA Cup. Compete with local rival Manchester United for the championship.

If Manchester City wins three games, UCL, EPL and FA Cup will all win the championship.

In this case, the football statistics website "Live Ball" uses the information of the gambling company "FiveThirtyEight" to determine the probability that Manchester City will win every game.

The EPL champion of Manchester City has a probability of 99% if only one victory is added.

Failing to win the championship in the "Star Wars", UCL, with a strong frog image in the well, won 74% of the championship probability.

The probability of Manchester City winning the FA Cup is 75%.

Jeffers： It is debatable for Tashuai to give up this season. Odegard needs to pay attention to physical fitness.

Arsenal lost to Nottingham Forest, Manchester City won the Premier League title ahead of schedule, and the Gunners’ performance at the end of this season was disappointing. Artta admitted at the press conference that the team gave up the championship competition this season and the coaching staff was responsible. Francis jeffers, a former English star, was annoyed by the mentality of his old club. He thought that the Arsenal had lost its spiritual system. Jeffers said: It is debatable that Tarzan gave up this season. Arsenal’s strength is not as good as Manchester City’s, and the thickness of Tarzan’s lineup is not good. However, these conditions are not the reasons for Arteta to give up this season. Even if the team’s hope of winning the championship is getting smaller and smaller, Tashuai should let the players cheer up in the rest of the game, instead of letting everyone "prepare for next season’s work in advance". This young marshal’s behavior is debatable.

Odegard, Saca and others have performed well this season, and jeffers also said "Monday morning quarterback" that Odegard is basically the MVP of this season if the Gunners can win the Premier League title with all their might. It’s a pity that the players and coaches were slack at the end of this season. jeffers reminded the Norwegian star, Odegard, that he needed to pay attention to physical problems. He obviously encountered physical problems in these games. Since Arsenal’s exit from the Europa League, jeffers said that the schedule of this club is not intensive. Even if these young players can’t rotate throughout the season and the gunners’ lineup is thin, their physical fitness should recover in the later stage of the schedule. Odegard is only a young man in his twenties, at least his physical fitness is far from the Premier League standard, which is a problem that Norwegian stars need to pay attention to.

Regarding the "collapse" of Arsenal in these games, jeffers said bluntly that Tashuai gave up this season after knowing that the team could not compete with Manchester City. The coaching staff began to give up, and the players’ nerves will naturally relax. Nottingham Forest itself will be relegated through these games, and the mental state of both sides is not at the same level. The reason why Arteta’s action is debatable is that the fans are divided into two factions. Some supporters believe that Arsenal’s goal this season is to enter the top four in the Premier League. Now that they have won the runner-up in the Premier League, Tarzan has overfulfilled the task. The lineup of the club itself is thin. At this time of the season, everyone is either injured or physically weak. It is no problem to give up preparing for next season in advance.

However, some fans who pay attention to the spiritual system don’t buy it. Before two games, the gunners still have the possibility of hitting the league title, but Guardiola leads the team to win the championship with a higher probability. However, there is still a Champions League game in Manchester City, and Arsenal only need to fight on one line. Artta should not give up at this time. Even if the Blue Moon Corps is stronger, it is easy for Gua Shuai to win the league title again, but the Arsenal side can’t lose the mental system, and "slacking off the game" is not desirable. Arsenal’s strategy in these games is debatable. Jeffers agrees with the latter point of view. No matter whether the team has the hope of winning the championship or not, even if the season enters garbage time, Tashuai can’t let the players relax. Because the gunners as a whole are in the recovery period of "post-Wenger era", the team and club must not lose their spiritual strength at this time.

Therefore, jeffers stressed that it is debatable for Tashuai to give up this season. The author thinks that this problem can also reflect Arteta’s lack of experience. He can take the team up, but when the team has setbacks, and this setback "will not be related to the coach crisis, at most, it will lose the championship, and it will not affect the qualification of the Champions League". It can be seen that Arteta needs to learn more from Mourinho and Guardiola in this respect. Regarding Odegard’s physical fitness, some fans don’t agree with jeffers’s point of view-Saka came to the fatigue period earlier than Odegard, and Saka was younger. Why did jeffers say Odegard instead of Saka? Is it because Saka is a native English star?

Jeffers explained this-Saka’s kicking method itself is very exhausting, because his running is mostly high-speed sprint, and if he doesn’t change his kicking method, he will easily accumulate injuries. Odegard is a "master-style" kicking method, and the way of Norwegian stars depends on the overall situation, consciousness and players, with little loss to the body. In this case, Odegard has physical problems, and he is still so young, so he should pay attention to his own problems. Now that Odegard has become the next generation leader of Emirates Stadium, he should demand himself by Premier League standards in all aspects. So jeffers reminded Odegard to pay attention to physical fitness.
