The results show that Sb addition can diminish the crystal grain, but the content of segregative phase at crystal boundary increases, and the current efficiency of material is low. Compared with Sb addition, Sn addition can also diminish the crystal grain, the current efficiency increases, the content of segregative phase at crystal boundary reduces, but diffusional corrosion of the anode surface is not uniform. The cooperation of Sb and Sn can prevent Si from segregating effectively and enhance the current efficiency obviously. At the same time, anode materials have preferable surface dissolution characteristics.

So far, it is not very clear why the delayed postarc restrikes occur. In this thesis, two kinds of restrikes have been discovered through prebreakdown current measurment and analyses,(1) the abrupt breakdown, it is characterized by a suddenly appeared, with a period of a few microsecond prebreakdown current, it is initiated by particle. This kind of restrikes can be reduced by decreasing loosly adhesive clumps which drop into the gap after arc extinction.

弧后延时重击穿的起因尚不清楚，本文通过对预击穿电流的测试和分析，发现这种重击穿主要有两种类型：（1）突发性的击穿类型，其特征是击穿前看不到预击穿电流的增长过程，预击穿电流的形成只有数微秒时间，这种击穿是由颗粒引起的，减少大颗粒脱落可以降低这种击穿的几率。
