以宁静磁尾平衡解为初态，本文考虑介质的可压缩性，对GEOTAIL卫星于亚暴事件中，观测到多重等离子体团与高能离子爆相对应之特征作模拟研究．数值结果表明：重复形成的等离子体团是高温、高密度区，揭示了等离子体团与高能离子爆──对应的动力学原因．本文的模拟结果还表明：大尺度等离子体团的地向运动，与X中性点的尾向迁移及地向流动增强相对应，而上述现象与驱动入流沿着边界的分布形态（即电场E的分布）有关．
In this paper, we consider the compressibility of the medium by considering the magnetostatic tail equilibrium solution. In this paper, we simulate the corresponding characteristics of multiple plasma clusters and high-energy ion explosions observed in the GEOTAIL satellite during a sub-storms event. The numerical results show that the plasma clusters formed repeatedly are high-temperature and high-density regions, revealing the plasma clusters and the high-energy ion explosions-the corresponding kinetic reasons. The simulation results of this paper also show that the geostrophic motion of large-scale plasma clusters corresponds to the tail-migration and the geostrophic enhancement of the X-Neutral point. The above phenomena and the distribution of driving inflow along the boundary (ie, the electric field E The distribution).
