应用锰铜压力计对钝感高能炸药JB9014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JB9014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 JB9014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，JB9014炸药的冲击感度均比具有相同TATB／粘结剂配比的PBX-9502炸药的低。

The 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℃．
