When reporters try to summarize the 30 years of changes in China's science and technology development, their hearts are embarrassing and uneasy. With 30 years of development, people are afraid to leave behind any memorable details. Thus, he tried to outline the context of 30 years through one case, one item of achievement, and one piece of data. However, the transfer of ideas reveals that science and technology are at hand. The elements of technology have penetrated into every aspect of our lives and have quietly changed our lives.
As we all know, China uses the global 7% of cultivated land to feed about one-fifth of the world's population. The creation of such a miracle is inextricably linked with the cultivation of high-quality seedlings and advanced planting methods. The hybrid rice developed by Yuan Longping, a famous agricultural expert in China, has been promoted on land of at least 15 million hectares in China, laying the foundation for safeguarding China's food security. Now, the agricultural expert who is over seventy years is still working toward a higher goal. He said: "The third phase of the large-scale demonstration of the target of 900 kilograms per mu, I am full of confidence in this, plans to achieve this goal in 2010."
In addition to the famous hybrid rice, China's cotton breeding experts have successfully studied the insect-resistant cotton, making China the second country after the United States to have independent intellectual property rights of transgenic insect-resistant cotton. According to statistics, in recent years, China has newly cultivated more than 800 new varieties of crops, with an average increase of production of more than 10%, and an accumulative total area of ​​nearly 500 million mu. This has enabled the coverage of major varieties of grain, cotton, oil, etc. in the country to reach around 85%. The contribution rate of progress to agriculture has increased from 37% in the “Ninth Five-Year Plan†to 48% in the “Tenth Five-Year Planâ€. Today, people who have already solved the problem of "eaten food" have eaten better and better. Fresh cucumbers, tomatoes, watermelons and other fruits and vegetables appear on the dining tables at home in the winter.
Not only change the "eat", science and technology are still quietly changing people's "walk." Thirty years ago, the average speed of railway trains in China was only 54 kilometers. With the opening and operation of the Beijing-Tianjin-Tianjin High-speed Railway on August 1, the maximum speed of Chinese railway trains has reached 300 kilometers per hour. In the peaks of the Qinghai-Tibet Plateau, the Qinghai-Tibet Railway, known as the miracle of the frozen world, was opened to traffic. The plateau “Tian Luâ€, the highest altitude and longest line in the world, crossed the life of the Tibetan Plateau. In the restricted area, in no man's land, and in the 550-kilometer permafrost area, scientific research workers have paid nearly 50 sets of time.
It is worth mentioning that during the Olympic Games, 75 hybrid cars developed and produced by Chinese enterprises were incorporated into the taxi fleet to drive in the Beijing area. Going out to play a new energy vehicle became a street scene. Not only that, during the Olympic Games, Beijing also invested 500 new energy vehicle service inside and outside the stadium, and for the first time in the history of the Olympic Games, it has achieved "zero emissions" in the Olympic center area. These energy-saving and environmentally-friendly vehicles are the independent research and development achievements supported by the national "863" program. In the future, the implementation of the promotion and application of "ten cities and 1,000 vehicles" for energy-saving and new energy vehicles will be implemented. At that time, people's travel will be more "green."
In addition, in terms of “useâ€, from multifunctional digital TVs to high-performance computers; from digital cameras, mobile phones, to MP3 players and other ingenious entertainment devices, people’s lives have entered into informatization due to the development of science and technology. The digital age. The rapid spread of Internet technology is affecting China's economic and social development at a deeper level. According to statistics, at present, there are more than 250 million Internet users in China, and the Internet has become an important tool for people to obtain information, entertainment, and work communication.
At the same time, the development of science and technology is also escorting people's health. After 30 years of hard work, China has basically changed the situation of lack of medical care and medicine. At present, it can produce 1,500 kinds of raw material medicines, and there are many varieties of the production of the world's first. With the development of biological and medical science and technology, many new drugs independently developed in China are also relieving pain for people. The recombinant human P53 adenovirus injection product independently developed by Shenzhen Synerino Gene Technology Co., Ltd. is “born again and againâ€, creating a tumor. A new situation in gene therapy; the only anti-diabetic drug “Taroâ€TM developed by the Academy of Military Medical Sciences, which has independent intellectual property rights, has brought good news to diabetic patients; “Recombinant Staphylokinase for Injection†developed by Chengdu Jinpeng Biotechnology Co., Ltd. "Applicable to the clinical treatment of multiple thrombosis, with good clinical application prospects...
For 30 years, technology has not only been a support for major engineering construction, but also has become a basic force for improving people's livelihood and promoting social harmony. For 30 years, technology has made our lives full of sunshine!
