叠氮化铅的等离子体电子作用机理初探

Research on mechanism of plasma electron effect of lead azide

本文分析了装有不同药剂的半导体桥(Semiconductor Bridge,SCB)火工品的电流信号,结合叠氮化铅(Lead Azide,LA)的铅核反应机理,探索性地分析了等离子体中电子对药剂分解反应的影响.表明SCB等离子体中的电子可能直接参与铅核的生成反应,使Pb^(2+)/Pb^0转化变得容易,实现6.89μs的发火.

Lead Azide （LA） was used to reveal the electron effect to the decomposition of primary explo sives in the Semiconductor Bridge （SCB） plasma. The current signals in different explosive particles as an important source were chosen to understand the mechanism of SCB plasma electron in the decomposi tion of LA. The conclusion is that the SCB plasma electron directly involved in the reaction of metal ion, can make the transformation of Pb2＋/ Pb0 easier and thus can be ignited in 6.89/us.
