In terms of physical technology, he has done a lot of pioneering work in China: 1954, he was responsible for the development of geomagnetic prospecting instrument (horizontal magnetic ruler), produced several sets for use by geological and geophysical departments, and won the achievement award of Northeast Branch of Chinese Academy of Sciences. 1963 promoted to associate researcher. Since 1970s, he has devoted himself to the research of vacuum ultraviolet-soft X-ray short-wave optics, opened up the field of short-wave optics in Changchun Institute of Optics and Mechanics, and established the technical foundation. He is the main pioneer and organizer of China's research work in this field. The research work has won the first, second and third prizes for scientific and technological progress of China Academy of Sciences. Starting from 1975, in order to establish a first-class optical metering station in national defense science and technology system, it is responsible for the research of "vacuum ultraviolet radiation standard". The standard light source of argon arc ultraviolet and vacuum ultraviolet with stable wall won the third prize of 1984 China Academy of Sciences for scientific and technological progress. 1983 was responsible for the optical pre-research of national synchrotron radiation beam line, and put forward the technical reports of "optical elements and monochromators in synchrotron radiation beam line" and "establishing radiation standards of ultraviolet and vacuum ultraviolet spectrum by synchrotron radiation", which were organized and implemented in Changchun Institute of Optics and Mechanics. 65438-0994, responsible for completing the key project of National Natural Science Foundation "Research on Basic Technology of Soft X-ray Optics", and establishing a relatively complete technical foundation of soft X-ray optics application in multilayer film technology, hyperspectral optical surface processing and detection technology, optical component and whole machine testing, normal incidence multilayer film imaging, etc. Won the first prize of scientific and technological progress of China Academy of Sciences; Second prize of national scientific and technological progress.
Comrade Chen Xingdan did a lot of pioneering work in China in 1950s and 1960s, and made important contributions to national economic construction and national defense research. In China's first nuclear test, he was responsible for measuring the light radiation power of the explosion. Without any data to follow, the measurement scheme is creatively conceived. An unmanned flux measurement system is proposed, which can automatically display the integral value of "light pulse" and is safe and reliable without external power supply, site restrictions and environmental interference, and is convenient for data recovery after nuclear explosion. Design and develop optical radiation sensors with different working modes to solve the reasonable distribution of parameters such as large range, high sensitivity and short time constant. Coelostat calibration system is proposed to simulate nuclear explosion radiation, and an absolute radiometer is developed to realize quasi-calibration. Several kinds of optical pulse meters were successfully developed for the first nuclear test in China, and were selected as the necessary radiation measuring equipment for future atmospheric nuclear tests, which provided accurate test data for the killing effect and killing range of optical radiation and the change of optical pulse with equivalent, weather, distance and explosion.
In the mid-1970s, China opened up the research field of short-wave (vacuum ultraviolet to soft X-ray) optical technology, put forward pilot and systematic scientific research projects, presided over the development of ultraviolet vacuum ultraviolet external wall argon arc standard light source and rare gas ionization chamber standard detector, and established the standard of short-wave spectral radiation intensity. Presided over the development of soft X-ray Pan Ning light source, double plasma light source and vacuum ultraviolet cathode light source, forming a series of high-performance spectral light sources covering 8nm-200nm. A series of normal incidence and grazing incidence monochromators and spectrometers with different wave bands and different applications have been developed. It is planned to carry out research on soft X-ray multilayer film and its supporting technology, train talents through international cooperation, develop coating and testing equipment, and study ultra-smooth optical surface processing and normal incidence soft X-ray imaging. A series of internationally advanced achievements have been made in the field of short-wave optical technology, and a complete technical foundation has been established in soft X-ray light source, components, metrology, normal incidence microscopic imaging and so on. It laid a technical foundation for the later important application research of space short-wave optical remote sensing instrument, synchrotron radiation beam line, soft X-ray microscopic imaging, soft X-ray space telescope and soft X-ray projection lithography. Therefore, 1989, 199 1 China academy of sciences first prize and second prize for scientific and technological progress, and 1995 second prize for national scientific and technological progress were the first winners.
Since the end of 1990s, he has been devoted to the research of near infrared spectroscopy technology and its application. On the basis of hosting the national key scientific and technological projects in the Seventh Five-Year Plan and the Eighth Five-Year Plan in the past, he presided over and completed the national key scientific and technological project "Research and development of rapid detection technology and instruments for grain quality", and successively developed the "third generation" filter near-infrared diffuse reflectance spectrum analyzer. In recent years, many doctoral students and postdoctoral students graduated or left the station, which expanded the application of near infrared spectroscopy technology in tea, ginseng, coal burning, biochemistry and other fields.
