Abstract

To verify the hypothesis of electrical hot spots (HSs)—channels of local electrical breakdowns—the analysis of the electrical properties of condensed explosives and the evaluation of the electric field strength in shock-loaded dielectrics are carried out. It is established that conditions for electrical breakdowns can be created in the compressed zone of explosives due to polarization phenomena (electric field) and shock-induced electrical conductivity (free electrons). The position of the electric model of detonation kinetics are formulated. The results of the experiments with liquid nitromethane (NM) and monocrystalline PENT are explained.

关于爆炸物引爆动力学的电学模型

摘要为了验证电热点（HSs）--局部电击穿通道--的假设，对凝结炸药的电特性进行了分析，并对冲击载荷电介质中的电场强度进行了评估。结果表明，由于极化现象（电场）和冲击引起的导电性（自由电子），炸药压缩区可产生电击穿的条件。制定了爆炸动力学电模型的位置。解释了液态硝基甲烷（NM）和单晶 PENT 的实验结果。
