Ions are injected from the magnetotail to the ring current region in a dispersionless mode most probably by enhanced convective electric field that driven by steady southward interplanetary magnetic field ( IMF). 离子通量的变化大体上是无色散的。离子主要受南向行星际磁场(IMF)所引起的对流电场的驱动注入到环电流区域。
At the rapid recovery stage of Dst/ SYM-H index, the speed of loss process for ring current ions may also takes different stages. 离子通量的变化还表明在Dst/SYM-H指数的快速恢复期间,环电流离子通量的衰减速度也可以发生阶段性变化。

Ions are mainly injected to ring current region in a pattern of adiabatic drift motion driving by enhanced convection electric field during magnetic storms. 离子主要受磁暴期间的对流电场的作用,通过漂移的方式注入到环电流区。
Also during ion injection episodes, the ion drift paths opened and ring current ions were lost at the noon to dusk magnetopause soon after they were injected at the dusk side region. 在离子注入增强期间,离子的漂移路径是开放的,以致大量环电流离子从黄昏侧注入后快速地损失在黄昏至正午的磁层顶。
