ring current

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。

First, we changed the ring-electrode structure of the tradition VCSEL into the "double ring cruciform" electrode structure, to make the new electrode access to the inside of the light-hole, so that improved the uniform injection current.

首先，我们将传统的圆环电极结构VCSEL改良双圆环十字型电极结构，使电极接入到出光孔内部，从而使得VCSEL的电流注入均匀。
