自变电阻法测瞬时燃烧速度

INSTANTANEOUS COMBUSTION RATE MEASUREMENT BY THE METHOD OF "SELF-CHANGING RESISTANCE"

利用以金属粉作为可燃剂的药剂大都具有导电性这一特点,建立了一种测瞬时燃速的新方法——自变电阻法。此方法操作简单,测试周期短且不需特殊设备,能测得燃烧成长的全过程。

A new method to measure the instantaneous combustion fetes based on the property of electric conductivity of the delay composition and pyrotechnics which mostly contain, matal powders as the combustion materials——thus the method of ″self-changing resistance″. The method is easy to be operated and does not need any special apparatus. The distance and time for the reactant to reach steady-state combustion can be measured with the method, so it can be used to study the combustion phenomena.
