For an inductive intrinsically safe circuit, minimum arcing voltage shows the arcing characteristics and current reducing rate shows the inductive characteristics.

对本质安全电感电路，最小建电弧电压能反映电路的建弧特性，电流变化率能反映电路的电感特性。

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.

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。
