摘　　要：应用锰铜压力计对钝感高能炸药JB90 14在常温和 - 54℃下冲击起爆压力场的发展进行了实验研究。在 - 54℃下压力场的发展图像揭示出JB90 14炸药遵循均质炸药起爆机理 ,而常温下的这种图像表明其兼备均质和非均质炸药起爆机理 ;在 - 54℃下JB90 14炸药的冲击感度比常温下低得多 ;无论是在常温下还是在 - 54℃低温下 ,JB90 14炸药的冲击感度均比具有相同TATB/粘结剂配比的PBX 950The pressure evolution of shock initiation for IHE′s JB9014 at ambient and -54℃ was investigated experimentally using embedded manganin gauges.The pressure evolution observed in JB9014 at -54 ℃ shows homogeneous initiation mechanism,by comparison,these observed in JB9014 at ambient temperature show a combination of homogeneous and heterogeneous initiation mechanism.The results show that JB9014 at -54℃ becomes signicantly less sensitive to shock than at ambient temperature and that JB9014 is less shock sensitive than PBX 9502 with same TATB/binder ratio at both ambient temperature and -54℃.
