Under the base of it, also considering the characteristics of the multi-channel multistage rimfire gas switch, much study and experiments of the surface flashover along the PMMA insulator and the PMMA housing of the switch were done. Following conclusions were drawn: After introducing PMMA insulator among the board electrodes, the voltage of the discharging of the SF6 drops by 30%. With increasing of the pressure of SF6, voltage of the discharging descends more sharply. With PMMA spacer, the dispersing of the discharging voltage of the gas gap increased as compares to the unbridged gap, such increases in value of the discharging voltage become more obvious with the gas pressure increased.

Two kinds of silicon samples with distinct surface treatment, i. e., one surface was chemically etched and the other was unetched, were used to investigate the characteristics of leakage current and surface flashover of semiconductor under impulse voltage in vacuum. The experimental results showed that the surface conditions of samples affected these characteristics greatly. Before flashover, the Ohmic current was observed for unetched samples and the space charge limited current for etched samples, respectively. Meanwhile both samples showed quite different flashover tracks, and the surface-etched samples displayed a much higher onset voltage of flashover.

对采用和未采用表面化学腐蚀处理的半导体硅在冲击电压下的实验表明（参见 Zhang et al ， Applied Physics Letters， 2002），试品的表面状况对其泄漏电流和沿面闪络特性有着很大的影响：在沿面闪络之前，未经处理试品的泄漏电流表现为 Ohm 性电流，而表面处理过的试品表现为空间电荷限制电流特性；同时两类试品表面的闪络通道也表现出不同的特征，而采用表面化学腐蚀处理可以明显提高其沿面闪络电压。
