摘　　要：在自行设计的气体火花开关上，利用双脉冲回路，对纳秒脉冲作用下Ｎ２和Ｈ２的绝缘恢复特性进行了实验研究。结果表明，在静态不吹气情况下，Ｈ２的绝缘恢复时间明显比Ｎ２短。在吹气情况下，适当的气流速度即可使绝缘恢复时间明显缩短。This paper presents results obtained during experiment research on the insulation recovery of the rep-rate gas spark gap.Insulation recovery information has generally been obtained using a two-pulse technique while the nanoseconds pulse breaks down the gap.First,under static conditions(unblown),hydrogen gas allows an order-of-magnitude improvement in the recovery of an unblow spark gap. Under dynamic conditions(gas flow),gas between the electrodes allow a significant improvement in the switch recovery.
