摘要: 采用PCB138压力传感器测量了TNT、RS211、HLZY-1和HLZY-3等几种炸药水中爆炸冲击波远场的压力时间历程，计算得到了这几种炸药水中爆炸冲击波性能参数及其相似常数。研究表明，含铝炸药水中爆炸冲击波远场的传播服从指数变化的相似律，其冲击波性能比标准炸药TNT优越。含铝炸药HLZY-1具有较好的水中爆炸冲击波性能。

Abstract: Underwater explosion tests were conducted in a water tank withstanding the explosion of a 8-kg-TNT equivalent charge.The far-field pressure-time curves of TNT, RS211, HLZY-1 and HLZY-3 were measured with the PCB138 pressure gauges. The shock wave performance parameters and the respective similarity constants of various explosives were calculated. It is suggested that the underwater shock wave propagation of the aluminized explosives follows an exponential similarity rule, the shock wave performance of the aluminized explosives is better than that of TNT explosive, and the shock wave performance of HLZY-1 is best in the aluminized explosives researched in this paper.
