Biao CHEN (B. Chen) (1923 - ) was born in Fuzhou, Fujian Province. In 1941-1942 he studied in the Department of Civil Engineering, National Southwestern Associated University, and graduated from the Department of Physics, University of Nanking (Chengdu).

　  After 1947 he was engaged in theoretical astrophysics, solar physics and astrophysical dynamics etc., in Purple Mountain Observatory, CAS. He also took part in the construction of the Beijing Astronomical  Observatory (BAO) and the Solar Observatory of Yunnan Astronomical  Observatory. He was elected as a fellow of the Chinese Academy of Sciences (Academician) in 1980. He has successively become a senior research staff in Purple Mountain Observatory, Head of the Theoretical Astrophysics Department, director of Yunnan Astronomical Observatory, honorary director since 1982 and also a member of the XIIth IAU General Assembly (12th) (Solar activity). He made great contributions to the establishment of observations and researches of solar physics in China, and had wide science interests. He got important achievements in several aspects as follows, exploration of the 'astronomically meaningfully interpretable observations and information processing', design and manufacture of instruments in solar physics, atmospheric conditions of the solar observatory, solar activity cycle and the structure of solar atmosphere, etc. He also made great contributions in specific astronomical states of matter, plasma theory applied to astrophysics, and magnetohydrodynamics. Besides, he promoted the coordination of the nationwide observations of  solar activity in the 21st cycle's maximum year, promotion of the international cooperation of solar physics researches and preparation for the coming  21st cycle maximum year. In the first several years when he started his astronomical career, some high-level scientific achievements was made by him, such as the interaction between radiation and material, dense material, fluid dynamics in astrophysics, cosmology and philosophy. Since the 1950s, he got several important achievements as follows, astronomically meaningfully interpretable observations and information processing, solar physics instrument design, the atmospheric environments of the Solar observatory, solar activity cycle and the structure of Solar troposphere, etc. He  published more than 20 papers in solar physics and astrophysics.
