| 摘 要： | 本文在给定的电场和磁场模式下,利用引导中心的动力学方程,计算了在磁层亚暴期间同步高度处电子通量突增的过程。结果表明:在增长相期间,电子通量并不增长,甚而有下降的趋势,电子通量的突增,大约是在膨胀相的开始。突增事件是发生在地方时半夜到黎明,10点到18点这一时间内没有突增现象,18点以后又发现有突增现象。这些主要特征与卫星的观测结果相符合。

| Abstract: | With a given electric and magnetic field model calculation has been made in this paper on the process of the sudden increase of the electron flux at geosynchronous altitude during magnetospheric substorms by means of the dynamic equations of guiding center. The results are as follows. During the growth phase the electron flux does not increase; on the contrary, it tends to decrease. The sudden increase of electron flux occurs at the onset of the expansion phase. Sudden increase events occur at local midnight till dawn. There are no sudden increase phenomena from 10:00 to 18:00. But they are found after 18 :00. These features agree well with the observational data from the satellite. |
