摘要
半导体桥火工品是取代桥丝的理想火工品。本文根据半导体桥的点火特性,应用电能转化为热能、热传导和炸药的热爆炸三个方面的理论,建立了在电容放电和直流输入两种方式下半导体桥桥体的升温特性方程;并通过计算机运算绘图,验证了方程基本符合理论要求。文章最后指出升温方程需加入修正系数来进一步完善。
Semiconductor-bridge （SCB） is one of the best fire devices for replacement of the use of bridge-wire. Based on firing character of semiconductor bridge （SCB）, the author built a temperature rising equation versus capacitance discharge and direct current input respectively by the use of the theories of energy transformation from electricity to heat, heat exchange and heat explosion. Computerization of the equation roughly proved its accordance with theory. As a conclusion, the author suggested that correcting coefficient should be considered so as to perfect the equation.
