They seek the interests of the motherland and are respected by the people.鈥斺€擶ang Daheng In December 2009, at the demonstration meeting of the China Optical Science and Technology Museum, Wang Daheng, who was over 90 years old, entrusted his secretary to implore the participants: Please stop calling me "the father of Chinese optics".This is not the first time Wang Daheng has declined in good faith."I am a lucky man of the times." Wang Daheng often said that he is at most one of the founders of China's optical industry.In his view, the work he has done is done in the context of the international situation and under the promotion and promotion of the needs of national construction, and is not his own merit.In 1948, Wang Daheng returned to China with the ambition of serving the country.At that time, the country wanted to manufacture optical precision scientific instruments, but could not produce the material for making them - optical glass.Everything started from scratch in 1951.In 1951, Wang Daheng was ordered to build the Instrument Museum of the Chinese Academy of Sciences, which was the predecessor of the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences.Two years later, the first furnace of optical glass was successfully melted here, ending the history of my country being unable to manufacture optical glass.When formulating the "National Science and Technology Development Vision Plan from 1956 to 1967" in 1956, Wang Daheng proposed that China should build its own electron microscope. Soviet consultants believed that it was too difficult and China could not build it within the planned time. If it was needed, it could be purchased from the Soviet Union.When leaders of the Chinese Academy of Sciences came to inquire, Wang Daheng patted his chest and replied: "It can be done!" In just a few years, he led his team to develop representative results known as "Eight Big Pieces and One Soup" ("Eight Big Pieces" refers to 8 types of optical instruments, and "One Soup" refers to molten optical glass), laying the foundation for my country's domestic precision instruments.In 1964, my country's first atomic bomb was successfully exploded, with the contribution of the large-scale optical testing instrument developed by Wang Daheng and his colleagues.In 1970, the "Dongfanghong-1" satellite was successfully launched. The Earth observation camera developed by him and his team brought back clear ground images.In 1980, my country completed the test of a long-range launch vehicle launched into the South Pacific. He participated in the development of a ship's movie theodolite and a hull deformation measurement system... Talking about scientific research secrets, Wang Daheng always said: "Treat science honestly and with a scientific attitude." After returning to China for more than 60 years, Wang Daheng rarely published papers, but the articles, reports, and handouts he reviewed were numerous.When it comes to the history of optical development in New China, he talks about the contributions of others, but always downplays his own.After Wang Daheng learned about the American "Star Wars" plan in March 1986, he immediately wrote a letter to Deng Xiaoping with Wang Ganchang, Chen Fangyun, and Yang Jiaqi, proposing that we should keep up with the world's advanced level and develop our country's high technology.This letter received the attention of the central government and approved the implementation of the National High-tech Research and Development Plan ("863 Plan"), which effectively promoted the progress of my country's high-tech.After retirement, Wang Daheng has not been idle. He has been campaigning for the development of high technology, proposing the establishment of the Chinese Academy of Engineering and Technology, and suggesting that the country pay attention to the development of large aircraft... He said: "Scientific and technical personnel have a motherland, and they seek the interests of the motherland and are respected by the people." On July 21, 2011, Mr. Wang Daheng died in Beijing at the age of 96.(Yu Sinan) Source: "People's Daily" 侣刮淌拷官步贤土分汤还姿咏量毙
