通过对凝聚炸药爆轰产物JWL状态方程的研究，提出了一种用γ拟合法确定JWL参数的方法。该方法不需要圆柱体试验，比现有方法更经济、安全、方便、准确。用该方法研究了4种常见炸药TNT、C-4、PETN和HMX。通过与圆柱体试验给出的JWL状态方程的p-V曲线进行比较，表明γ拟合法具有较高的精度，满足爆炸力学应用的需要。
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.
