爆轰产物的状态用各种状态方程来描述。琼斯-威尔金斯-李（JWL）状态方程因其简单而被广泛应用。JWL状态方程包含由筒体膨胀试验确定的参数。我们通过一种适用于圆柱形烈性炸药水下冲击波形态的特性方法得到了这些参数。利用JWL参数计算得到的数值结果与实验结果进行了比较。在圆柱形和球形烈性炸药水下爆炸实验中，证实了两者之间的良好一致性。
State of detonation products is described by various types of equations of state. Jones-Wilkins-Lee (JWL) equation of state is widely used because of its simplicity. JWL equation of state contains parameters determined by the cylinder expansion test. We obtained these parameters through a method of characteristics applied to the configurations of underwater shock waves by cylindrical high explosives. The numerical results obtained by using the JWL parameters are compared with the experimental results. Good agreement between them is confirmed in the case of the underwater explosion of cylindrical and spherical high explosives.
