| 摘 要： | 通过高速照相，直接观察含铝ＰＥＴＮ炸药在落锤撞击期间熔化、点火和爆炸的过程，收集轻包实验后的固体爆炸产物，并对其进行扫描电子显微（ＳＥＭ）分析，发现铝在炸药爆轰过程中氧化燃烧的痕迹。使用ＤＹＴＲＡＮ程序，进行了相关的数值计算，从理论上描述了扫过含铝炸药热点形成的过程。

| Abstract: | The processes of melting,initiation and explosion of the sample of Al containing PETN are observed directly by a high speed photograph during impact, and the solid products of the sample after impact from the gas gun are studied by SEM analysis. The results show that the aluminum powder is oxidized and burns during detonation. After conducting the related numerical modeling by the DYTRAN code,the process of the hot spot formation in the sample around the aluminum grain is described theoretically. |
