参照ＬｅｅＥＬ等报道的有关铸装ＴＮＴ的ＪＷＬ形式状态方程及化学能释放率函数，从理论估算了不同反应率的定态雨贡纽关系和定常爆轰波结构；利用二维拉氏ＦＣＭ程序数值模拟铸装ＴＮＴ的冲击引爆、绕爆、隔爆等爆轰性能，对一些典型算例进行了计算，计算结果与文献给出的结果相一致。 Referring to the state equations of JWL and the chemical energy release rate function reported by LeeEL et al., The steady state rain gongnu relationship and steady detonation wave structure with different reaction rates are estimated theoretically. Two-dimensional Laplace FCM program is used Simulated cast TNT impact detonation, around the explosion, explosion and other detonation performance, some typical examples were calculated, the calculation results and the literature gives the results are consistent.
