A Simplified Model of the Magnetopause and the Lower-hybrid-drift Instability
-
摘要: 本文从简化的李-甘分布函数出发讨论了磁层顶中的低杂漂移不稳定性,并与漂移麦氏分布算得的结果作了比较.用电流弛豫方法求得了饱和电场扰动的振幅,这振幅与观测值5mV/m相一致.Abstract: The paper discusses the lower-hybrid-drift instability in magnetopause from the simplified Lee-Kan distribution function. The results are compared with those obtained by the drift Maxwell distribution function. The saturated amplitude of the electric field perturbation is evaluated by current relaxation. It is consistent with the data observed-5mV/m.
