如果将火花试验装置的电极在闭合或断开时的放电电弧看作一个非线性电阻，则可以实现电路本质安全性能的计算机辅助分析方法。

If the arc generated during the make or brake of electrodes of spark-test apparatus was regarded as a non-linear resistance, non-explosion assessing intrinsic safety method can be established.

在火花试验装置上进行爆炸试验，得到本质安全复合电路的放电波形，发现电弧电压基本维持在最小建弧电压，而电容电流随着电路参数的不同而发生振荡。

It was found that when the capacitive ignition occurred, arc voltage will keep minimum arcing voltage, but arc current possibly attenuates in sinusoidal form with different circuit parameters.
