calefactive

1.Thermal ignition temperature was defined,the thermal ignition process of electric hot wire initiating devices was divided as calefactive phase and explosion phase.

定义了热点火,丝式电火工品的热点火过分为阶段和爆炸阶段。

2.In calefactive phase, the electro thermal model of hot bridge wire was established, the calefactive time of invariable current fire case and capacitance discharge fire case were both studied.

阶段建立丝电热模型，分别求解恒定电流点火时间和电容放电点火时间。
