The team of Tsinghua University has developed ski prosthetics and developed thermal protectors for paraplegic athletes who are insensitive to cold perception; Domestic intelligent bionic hand helped Jia Hongguang with upper limb disability successfully complete the torch relay of the winter Paralympic Games On March 2, torch bearer Jia Hongguang passed the city's kindling torch on the round hill of the temple of heaven. Photographed by Xinhua News Agency reporter Xia Yifang In this winter Paralympic Games, we saw more advanced, more yuan and more considerate technology to help the disabled, which not only provided more comfortable and convenient life for athletes, but also helped athletes improve their performance. There will be more applications of science and technology to help the disabled in the future. For example, visually impaired athletes need leading skaters for skiing. With the development of communication technology, video is transmitted to leading skaters in real time. Visually impaired athletes may be able to complete alpine skiing competitions independently by "online" listening to tips. Obviously, scientific and technological progress is bringing more possibilities to disabled athletes. This can not help but make people wonder whether the disabled athletes will surpass the healthy people in some events in the future? With the development of science and technology, when it becomes a routine operation to improve the body function and complete the difficult movements of the body through instruments - as we can see in science fiction movies, how much difference is there between the disabled and the able-bodied? In fact, athletes with physical disabilities have been able to gallop on the field like healthy athletes. Thanks to this new material, carbon fiber, amputees can use lightweight, elastic and compact prosthetics or running "blades" to replace their lower legs and ankles. The popularity of carbon fiber prostheses is an important watershed in the history of the Paralympic Games. In the track and field field, the 100 meter performance of amputees has never exceeded 13 seconds before. After the emergence of carbon fiber prosthesis, the performance of athletes began to make rapid progress. Now in the fastest group, this record is not far from the 10 second mark. On May 30, 2016, German athlete Marcus rem, the champion of long jump in the London Paralympic Games, took a photo with a prosthetic limb. Shen Jizhong Don't be surprised if one day you see the results of the winter Paralympic Games surpassing those of the Winter Olympics! This is likely to happen. Of course, the potential and technology of the body need to be further improved. In the ongoing Beijing winter Paralympic Games, although six events are the same as the Winter Olympic Games, the race track and competition system are different. For example, the length and difficulty of snowboarding events are reduced. Objectively speaking, the results of athletes in the winter Paralympic Games can not catch up with the sound people. This is mainly because the training methods for the disabled are not as complete as the healthy people, and the disability assistance equipment has not been able to make up for the differences in physical conditions between the disabled and the healthy people. With the passage of time, perhaps these two points will not become a problem objectively. Of course, the best way to measure the level of athletes is to compete in the same game. In terms of rules, the Olympic Games do not exclude disabled participants. As long as the results reach the Olympic qualification line or pass the Olympic qualification competition, disabled athletes can also participate in the Olympic Games. Disabled athletes have participated in the Olympic Games in table tennis, triathlon, track and field and other competitions. On March 11, Chinese athlete Liu Mengtao won the championship in the men's long distance (sitting position) competition of biathlon in Beijing winter Paralympic Games.

To some extent, it is precisely because it will cause unfair competition that there are Paralympic Games and other events for the disabled. On the contrary, disabled athletes may also gain competitive advantage over healthy people through disability assistance devices. We have already had such examples. Two legged amputees once participated in the men's race with "blade prosthesis" at the 2012 London Olympic Games. However, later, the international Athletics Federation (now the World Athletics Federation) organized a group of experts. After measurement and analysis, it is believed that the carbon fiber prosthetic running of disabled athletes saves 17% of effort than that of healthy people, which constitutes a new unfair competition. The modern Olympic movement has developed for more than a hundred years, and its core value is to challenge the physical limits of mankind. Therefore, in the era of technological explosion, the helmsmen of the Olympic Games have been carefully adjusting and controlling the boundaries of the use of high-tech equipment and technology. Otherwise, the "Alpha dog" sweeping the world go masters in the field of intellectual sports may have also happened in the Olympic Games. I believe that with the passage of time, the renewal of technology and the change of concept, we will inevitably face the problem of Sports Ethics - what role should science and technology play in competition and how to keep the bottom line of fair competition? At the same time, we also believe that mankind will be able to solve this problem and make it conform to the trend of the times without giving up the bottom line of value.

No matter where science and technology go, the original intention of the Paralympic Games is to stimulate potential, rebuild confidence, and obtain courage and hope. Both sports and science and technology are the help of mankind to create a better future. People oriented is the starting point and foothold of everything. (Xinhua News Agency)
