在氙气灯内，电流通过一个充满气体的显像管，弯曲成弧形。
This is commonly a xenon lamp, in which electricity is arced through a tube filled with the gas.
所以气体流量一定要与切割电流和速度很好的配合。
So the gas flow must with cutting current and speed very good cooperation.
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。
In this region, its thickness and potential fall are mainly determined by discharge current and gas pressure.
