| 摘 要： | 采用飞片碰撞技术，在TNT/RDX（40/60）炸药中获得了2.5倍于正常爆轰的最大超压值，得到了超压爆轰下爆轰产物物态方程p=Aρk+A1(p-pJ)（p－爆压，单位GPa，ρ－密度，单位kg/m3，A=ρJ/ρkJ，pJ=27.06 GPa，ρJ=2.3×103 kg/m3，k=2.77，A1=2.7×10-3 GPa-1，下表J代表正常爆轰状态）。该方程还可以较好地描述超压爆轰产物的二次冲击状态。

| Abstract: | Maximum detonation pressure of 2.5 times than its C-J value was obtained in TNT/RDX (40/60) by using planar flyer impact technique. The equation of state of overdriven detonation product was derived as the form of p=Aρk+A1(p-pJ) (p－detonation pressure, GPa, ρ－density, kg/m3, A=ρJ/ρkJ, pJ=27.06 GPa, ρJ=2.3×103 kg/m3, k=2.77, A1=2.7×10-3 GPa-1). The reflected shock state of the overdriven detonation product could be also described by the above equation satisfactorily. |
