最后提出了电弧自熄判据，并以此计算了燃弧时间，与实测时间基本吻合。

Finally arc self-extinction criterion is proposed to compute arc durations under the different conditions, which are corresponded with test results.

结果表明，采用本文所建立的模型进行预测时，预测值与实测值更接近；

The results show that the predicted values of the new model are closer to he measured ones than those of the traditional model;
