863 project proponent, bombs and one satellite Meritorious Scientist Wang Daheng
” bombs and one satellite Meritorious Medal “winner, Chinese Academy of Sciences, Chinese Academy of Engineering, Fellow of the International Academy of Astronautics, the famous optical home China’s modern optical engineering major academic founder, pioneer and leader in the organization, an outstanding strategic scientist, educator Mr. Wang Daheng, illness in at 13:02 on July 21, 2011 in Beijing, died at 96 years old.
smelting furnace of China’s first optical glass
Wang Daheng born 1915, native of Jiangsu Wuxian. 1932, 17-year-old Wang Daheng obtain Tsinghua University, though his father told him that physics would be poor for life, but Wang Daheng still insist on their own choice, because he had heard the famous Tsinghua University physicist leaves Enterprise Sun, Wu Xun, Zhou Pei-Yuan and other masters.
Wang Daheng Mr. Ye Qisun is the most admired, one of the most respected teachers. After the outbreak of the war, Mr Yip has taught students to recognize their historical mission. Since then, “My home is in the northeast Songhua River,” a favorite song, Wang Daheng.
1938 years, Wang Daheng obtain a scholarship to study abroad in the British Boxer qualifications. Two years later, he won the British Imperial College London, optical technology, professional master’s degree.
during World War II, due to the important position in the military, optical glass was then the Western countries regarded as an important security technology. To learn that China has not the technology, Wang Daheng 1941 transferred to the University of Sheffield in the UK glass manufacturing technology department, PhD. However, the second year, he gave up his doctorate, select the companies in the UK Chang Division of glass optical glass research.
Wang Daheng hard to study in the UK for 10 years, complete control of the optical glass research, design, manufacturing technology, in 1948 returned to the motherland. After that, he led the scientists smelting furnace of China’s first optical glass, optical glass is not the end of China’s history.
less than a year to come up with the atomic optical measuring instrument
1999 September, countries in the “bombs and one satellite” to make the development outstanding contributions to the 23 scientists awarded “bombs and one satellite” Meritorious Medal. Wang Daheng This is the most open in the public eye once the most solemn appearance.
the 1960s, the Chinese atomic bomb test is imminent, and optical measuring equipment unfunded. Wang Daheng developed the burden fell on the body. Wang Daheng struggling to research, less than a year to produce a qualified instrument.
medium-range missiles developed by China, Wang Daheng higher level body to provide measurements of orbital space flight and the flight attitude of the large-scale observation equipment. At that time, there is only one country to master this technique, but their foreign blockade.
Wang Daheng proposed overall program, in coordination with the parties, an instrument developed for China’s medium-range missile launch, and after the ICBM launch, flight test satellite measurements provide valuable data and image data.
until recent years, China’s “Shenzhou” series of spacecraft launches, Wang Daheng then lead the development of optical theodolite film continues to play an important role.
satellite create “artificial Little Sun”
before our man-made earth satellite into space, in order to ensure the normal operation of the satellite can fly in space, to the ground simulation of solar radiation. This requires developed a solar simulator called the “small artificial sun.”
the beginning of the design are: use 37 5 kW xenon lamp group put together. But this group to fight as long as a light run disorders, testing can not proceed. Later, Wang Daheng that the successful development of high-power xenon lamp in the news, immediately changed the original design, made using new high-power xenon lamp technology to reduce the number of xenon to 19, and finally the construction of a light diameter of 4 m solar simulator, was successfully used to simulate meteorological satellite of the sun exposure trials.
optical measuring sea founder
in the “afar” was scientific expedition on board for optical measurement, is a highly difficult task. Everyone knows that the optical measurement must have a stable work environment. The “Yuanwang” in the Sea, a strong swing in the hull in waves, it is impossible to have a stable work environment.
To capture this issue, Wang Daheng and his colleagues repeated the experiment out to sea for optical devices. He and “afar” was the chief architect to discuss the chimney moved to the stern, optical instrument into a relatively stable boat center. After Wang Daheng led us to a wide range of research, creative solutions to measure the stability of the world’s ocean space tracking, positioning, calibration and anti-jamming and other technical problems for China’s long-range rocket test, geostationary satellite tracking to make an outstanding contribution.
Wang Daheng of this achievement won the national scientific and technological progress.
that “863″
Mr. Wang Daheng vision, thinking strategically and in conjunction with other scientists on the national science and technology development for a number of major recommendations made .
1986 年 3 on 3, Wang Daheng and Chen Fangyun, Wang Ganchang, Yang Jiachi four old scientist letter to the CPC Central Committee, made follow-up study of strategic high-tech proposals.
plan reported to the central two days, Deng Xiaoping, that is made in the report instructions. CPC Central Committee and State Council quickly approved and implemented the “high-tech Research and Development Plan.” People to four days recommended by scientists, it is called “863″.
Jiang Zhuying his students
national model Jiang Zhuying (1938-1982) is in Hangzhou, 1956, admitted to Department of Physics, 1962 Wang Daheng obtain a graduate student in Changchun Institute of Optics and Fine Mechanics Institute.
Jiang Zhuying first in the country to establish an advanced optical transfer function measuring device. In the 1970s, China’s color TV technology is very backward recovery, leading to severe color distortion. Jiang Zhuying together with the tutor Wang Daheng research, quality of proposed new color restoration program, and finally break up the technical difficulties, making it possible to see a clear image, vivid color color television.
1982 June, Jiang Zhuying due to overwork, in Chengdu, when traveling, died aged 43.
