为确定高烈性炸药的JWL参数，进行了筒体膨胀试验。利用JWL参数，对高能炸药水下爆炸产生的水下冲击波进行了数值模拟。结果表明，水下激波在爆炸点附近的表现与远离爆炸点的表现有很大的不同。特别是在炸药附近，由于气体产物膨胀的影响，水下冲击波的强度迅速降低。
A cylinder expansion test for high explosives was carried out to determine JWL parameters. Using the JWL parameters, we carried out numerical simulations of the underwater shock waves generated by the underwater explosion of the high explosives. Our results showed that the behavior of the underwater shock waves at the vicinity of the explosives differs greatly from that far from the explosives. Especially, the strength of the underwater shock wave nearby the explosive rapidly decreases due to the effect of the expansion of the gas products.
