中文摘要	选用了1974-07-06,1982-03-02和1982-09-06三次强地磁活动时的Ap值,由AE-C和DE-B卫星所测得的热层成份数据,进行统计分析,结果表明;在强地磁活动期间,热层大气密度涨落变化十分清晰,涨幅随高度增高而增大,高度600km附近涨幅可直达4倍,热层大气成份中N2的数密度涨幅最大,而原子氧的丰度在强地磁活动期间明显地下降.
英文摘要	In this paper, the Ap values for three geomagnetic activities of Jul. 6, 1974,Mar.2, 1982 and Sept.6, 1982, and thermospheric composition data from AE-C and DE-B are used to search the change of the thermospheric composition and density during severe geomagnetic activities. The results show that the fluctuation of thermospheric density is very clear during severe geomagnetic activities. And the magnitude of this change increases as the altitude increases. At near 600 km,the change can be four times of the original values, the change of NZ density is the largest in all of the thermospheric compositions; while the abundance of O (No/Nal)decreases notably during severe geomagnetic activities.
