摘　　要：采用简化模型 ,假定高压下冲击产物全部转变成金刚石和原子氢 ,计算了苯的理论物态方程。理论羽贡纽曲线与实验结果在高压段较为符合。分析了模型的局限性。从结果分析推断在 4 0GPa以上 ,产物中石墨相全部转变成金刚石。Theoretical equation of states of benzene is computed by a simplified model on the assumption that shock products are diamond and H atoms entirely at high pressure. Theoretical Hugoniot is consistent with experimental data at high pressure. The availability of this model has been analyzed. It is deduced that graphite phase has fully transformed to diamond in shock product above 40GPa.
