【摘要】 通过测量铸装TNT/Al与压装TNT/Al混合炸药爆轰过程的电导率,得到了含铝炸药二次反应时间与主体炸药及铝粉粒径之间的变化关系。根据电导率测试实验原理,提出了新的测试电路和计算公式,分析了电导率随时间变化的内在影响机制。结果表明,铝粉越细二次反应起始的时间越早。更多还原

【Abstract】 By measuring the electrical conductivity during detonation process of aluminized explosives such as cast TNT/A1,press mounting TNT/RDX/A1,the relationship between the secondary reaction time of aluminized explosive,the matrix of explosives and the particle size of aluminum powder was obtained.According to the experimental theory,a new test circuit and formula for calculating the electrical conductivity was presented,as well as the within mechanism of electrical conductivity over time variation.The results showed that the smaller aluminum powder,the sooner secondary reaction started.更多还原
