目的：研究大威力弹头爆炸时破片复合冲击波致伤动物的伤情。方法：以某大威力弹头为爆炸源，电引信引爆，动物围绕爆心呈扇形布放，于伤后０～７２ ｈ 内作大体解剖观察。结果：破片伤的发生率高达８６．７％ ，且是近爆心动物伤后即刻和早期死亡的主要原因。冲击伤的发生率为８２．２％ 。结论：破片和冲击波是大威力弹头爆炸时的主要致伤因素，且高速破片有加重冲击伤的作用。 OBJECTIVE: To study the injury caused by the compound shockwave-induced injury in the Grand Warhead Explosion. Methods: With a big warhead as the source of explosion, the electric fuze detonated. The animals were placed in fan shape around the heart of the abdomen, and the gross anatomy was observed within 0 ~ 72 h after the injury. Results: The incidence of fragment injuries was as high as 86.7%, and was the main cause of immediate and early death of near-hearted animals. The incidence of impact injuries was 82.2%. Conclusion: Fragment and shock wave are the main injury factors in the explosion of large-power warheads, and high-speed fragments have the effect of aggravating the impact injury.
