摘　　要：在温度为 2 0℃、- 30℃和 - 54℃条件下 ,用半球形传爆药输出的发散冲击波引爆密度1 90g/cm3的塑料粘结TATB钝感炸药 ,采用“切面实验”方法 ,通过电探针测试技术 ,观测了炸药中被引发的爆轰波或反应冲击波速度的增长或衰减过程。实验表明 ,温度降低 。The behaviours of plastic bonded TATB initiated by divergent shock waves were studied experimentally at 20℃,-30℃ and -54℃,respectively.The divergent shock waves were generated by a hemispherial train of high explosives.Detonation (or reactive shock) wave velocities in the explosive were determined using “section plane” method and electrical pins.The experimental results show that temperature variation affects the initiation behaviour of the TATB remarkably.
