In this region, its thickness and potential fall are mainly determined by discharge current and gas pressure.
在这一区域内，阳极位降、阳极位降区厚度主要由放电电流和气体压强所决定。

The results show that the reflection coefficient near the wall is about 0. 59, and in the plasma of the first discharge after a gas change, the wall-released isotope amount to 65% .
