摘　　要：采用炸药爆炸冲击加载的方法,对PBX炸药进行冲击损伤实验,测试炸药冲击前后的密度变化,并利用扫描电镜(SEM)对炸药的剖面进行细观观察,同时对损伤炸药的冲击起爆过程进行了实验研究.通过比较不同损伤程度PBX炸药的压力变化历史得到,炸药损伤越严重,波阵面成长越快,冲击感度越高.Impact damage to PBX explosives was produced by explosive detonation and its measured. The meso-structure characterization of damaged explosives was studied making scanning microscopy. It carried out the study of shock initiation at the same time. The results that the wave blast surface was raised and the sensitivity increased to damaged explosives.
