| 摘 要： | 由吉布斯自由能最小计算处于化学平衡状态的气体和固体混合系统的平衡组分。以BKW和VLW作为爆轰产物的物态方程对几种炸药爆轰参数作了预言，计算结果与实验值吻合得非常好。另外，还对CHBr3的冲击压缩分解作了化学平衡计算，给出了冲击压缩曲线，对文献6]中提出的CHBr3在55~60 GPa存在相变的看法提出了质疑。

| Abstract: | The equilibrium compositions of the gas-solid mixture are calculated by minimizing the Gibbs free energy and chemical equilibrium. BKW and VLW equations are proposed for the EOS of detonation products and the detonation properties of explosive composed of C-H-N-O have been calculated. The results are agreed with experiment data excellent. Moreover, the equilibrium calculations are conducted on the dissociation of shock compressed liquid bromoform and our numerical results agree with reported shock-wave data. The analysis based on our numerical results suggests that at 55～60 GPa there occurs a continuous shock dissociation rather than a thermodynamic phase transition. |
