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.

为较好地实施该工艺，电弧炉主要工艺参数及辅助条件应与之相适应。

This article describes the optimized process parameter and method for the arc furnace design and operation, as well as the other auxiliary conditions.
