摘要： 本文用"空间和能量双向一维差分方法",数值解了带有能量弥散项的高能带电粒子的Fokker Planck方程。在此基础上计算了对背景等离子体的总能量输运,以及转移给电子和离子的能量份额。所得经果与其它方法的计算结果进行了比较。

Abstract: The charged particle Fokker-Planck equation including the energy dispersion term is solved with "one-dimension difference method of both the space and the energy". On the basis of the results obtained, the total amount of energy transfer to background plasma and the fraction of energy transfer to the electrons and to the ions are computed. The results obtained are compard with that computed by the ether methods.
