摘　　要：我国“风云一号(B)”气象卫星于1990年9月3日发射入轨,该星载有粒子成分监测器,用来探测空间粒子辐射环境,其中包括测量太阳耀斑时产生的太阳质子事件及其重粒子丰度;银河宇宙线异常成分与强度;内辐射带磁异常区的粒子通量及重粒子成分,“风云一号(B)”卫星运行半年来,我们已获取了上述有关的粒子辐射资料,在卫星上获得这些资料在我国尚属首次,本文主要分析观测到的太阳质子事件。This paper analyses the solar proton events observed by the cosmic ray composition detector on board the Chinese 'Fengyun 1' (FY-1) meteorological satellite.They include the events on Sept.4,1990 and on Feb.l and 2,1991 especially the later events are observed by the Rio-meter at the antarctic Zhong Shang station and by the superneutron monitor at Beijing Station.This shows that the events include the solar protons with very high energy and have very wide energy spectrum.Besides solar protons,a particles,carbon,nitrogen,oxygen and iron particles are also observed at the same time.It is the first time in China that the solar proton events roton event,Solar flare
