| Abstract | 计算了高能脉冲电子束在冷背景和热背景等离子体条件下产生的等离子体尾场（ＰＷＦ）大小，讨论了高能电子束的速度、密度、长度对等离子体尾场分布的影响．在这基础上，研究了太阳耀斑脉冲相产生的向外逃逸高能脉冲电子束在日冕背景等离子体条件下激发的等离子体尾场分布以及对其捕获电子的加速． |
| Other Abstract | In this paper we have calculated the plasma wake fields(PWFs) excited by the interaction of high-energy electron beam with cold and hot plasma, and discussed the effects of electron beam speed, density and its length on PWFs. Based on the obtained results, we have studied τ-profiles of PWFs resulted from the interactions of high energy electron beams produced during a solar impulsive flare with the cororonal plasma, and acceleration of lower energy electrons by this PWFs in the corona. Here τ=ωp(t-x/vb) where。，ωp(4πne/m,) and t，is time，x the axis along the diraction of electron beam velocity, v6 the speed of electron beam, no plasma density in the corona, and m, the rest mass of electron. |
