plate electrode slag pool welding

The relationship between plate electrode current and controlling voltage is observed, and this is helpful to explain the increase in combination probability of electon and ion around the second grid-electrode at high reflector voltage.

观测了电离情况下板极电流与反射电压的关系,阐明了在高反射电压下电子在第二栅极附近聚集会增加离子的复合概率。
