| 摘 要： | 通过对凝聚态炸药爆轰产物JWL状态方程的研究，提出了一种确定JWL状态方程参数的γ拟合法，即利用γ律状态方程来拟合JWL状态方程参数。这种新方法不需进行圆筒试验，与现有方法比较，具有经济、安全、方便、准确的特点。利用这种方法拟合确定了4种常用炸药TNT、C-4、PETN、HMX的JWL状态方程参数，通过与圆筒试验法得出的JWL状态方程p-V曲线进行对比，证明γ拟合法具有较高的精度，完全可以满足计算爆炸力学的应用。

| Abstract: | By investigating the JWL equation of state of detonation products of condensed explosive, we present a method to determine JWL parameters by γ fitting. This approach does not require cylinder test and is more economical, secure, convenient and accurate than existing methods. Using this method, four kinds of common explosive, e.g., TNT, C-4, PETN and HMX have been studied. By comparing to the p-V curve of JWL equation of state given by cylinder test, we showed that the γ fitting has a high precision and meets the need of explosion mechanics application. |
