Biography

Liu Guangjun, male, Hui nationality, is a native of Tianjin Municipality. He studied physics at Tsinghua University.

Liu served as senior engineer of the Nuclear Industry Physico-Chemical Engineering Research Institute. He has specialized in uranium isotope separation and significantly contributed to the application of diffusion methods and theory of centrifugal methods. Liu was also responsible for production and technological work while working at the plant. He participated in and organized many renovation measures, and successfully decided on the measures of technical renovation and improving cascade efficiency, making the production output and economic benefit of enriched uranium greatly improved. While acting as chief technical person-in-charge of the R&D of centrifuger, a national key project in 'Seventh Five-year Plan' period, Liu coordinated and organized six links of overall equipment R&D which significantly accelerated R&D speed.

Concerning the research of separation theory, Liu put forward three criterions for optimized running conditions of diffusion cascades, and introduced the spread rule of concentration interference. In the study of gas-kinetic theory, he initiated a new method of setting up Boltzmann equation-type model equations, and inferred entropy increment formula in gentle and rare gas.

Liu Guangjun was elected as an academician of the Chinese Academy of Sciences in 1991.
