摘　　要：为研究新型含能破片低速撞击并引燃屏蔽炸药的机理,对新型含能型破片进行了实验研究与理论分析。结果表明:含能破片对屏蔽炸药引燃的撞击速度为631～925m/s,远低于冲击起爆的阈值速度1450m/s,引燃机理为:含能破片冲塞后,破片内部的含能材料发生反应,释放大量的热,从而引燃炸药。To study the mechanism of new type reactive fragment low-speed impact and ignited charge, can type the new fragment containing the experimental research and theoretical analysis. The results showed that： reactive fragments on impact ignition of explosives screening at 631-925 m/s, well below the threshold of detonation shock speed of 1450 m/ s, the mechanism for ignition： reactive fragments after plugging, fragment containing an internal reaction to the material, the release of large amount of heat, which ignited the explosives.
