摘　　要：本文介绍“风云一号”(B)星上的“宇宙线成份监测器”于1990年11月19至24日对内辐射带质子的观测结果。通过对这些结果的分析,本文获得了4—23 MeV能量范围内辐射带质子垂直强度在磁坐标内的分布特征。同时,本文还给出了100°E子午面内质子垂直强度的分布。分析表明,所得结果与辐射带理论一致。The cosmic ray composition monitor on the board the Chinese Satellite, Fengyun-l(B), launched in September 1990, had detected the geomagnetically trapped particles (mainly protons, a particles, ions of Carbon, Nitrogen, Oxygen and Iron) for as long as more than 100 days. Both stationary and solar proton perturbed fluxes of the geomagnetically trapped protons have been recorded. This paper reports the results of 4-23 MeV protons obtained from 19th to 24th November 1990, a relatively quiet period of the geomagnetic field. The perpendicular flux distribution of the protos in the L-B space are obtained and studied. This paper also presents the perpendicular flux distributions of protons on a particular geographical meridian plane (100?E). The results are agreeable with the Radiation Belt theory.
