calefactive

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

定义了热点火度,将桥丝式火工品热点火过分为升阶段和爆炸阶段。

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.

在升阶段建立桥丝热升模型，分别求解恒定流点火升时间和点火升时间。
