简介：为高功率脉冲功率装置设计了4MV同轴-三平板型水介质自击穿开关作为脉冲输出开关。脉冲输出开关指在脉冲功率装置中脉冲形成线输出端的开关，它是脉冲形成线和传输线的连接部件，对传输电脉冲进行二次压缩。脉冲输出开关常常是自击穿开关，由于其前面的主开关对Marx发生器输出电脉冲进行了初步压缩，脉冲输出开关的输入脉冲前沿上升较快，故脉冲输出开关常常是多通道开关。

简介：从电子在电磁场中的狄拉克方程出发,得出电子在电磁场中波函数,分析磁矢热A引起的电子概率波的相移,结果表明:影响电子波函数的相位变化不是B而是A(x),即有一个额外相因子附加在电子概率波上,进而通过量子干涉出现图样的位移。结论是A—B效应的存在说明磁场的物理效应不能完全用B描述,而是附加在电子概率波上的相因子。
