摘要: 在原有的冲击温度计算方法的基础上提出了一种新的计算方法,它既考虑了电子对冲击温度的影响,也有效的回避了物质零温物态方程计算的困难。通过对金属铝和铜的计算,结果与实验数据吻合得很好,所给出的铝和铜的冲击熔化点分别为(125.5 GPa,4 705 K)和(231 GPa,5 369 K),与目前铝和铜的冲击熔化点的实验数据吻合得非常好。Abstract: Basing on the former shock temperature calculation methods, a new method was proposed, which considered the electronic contribution and successfully avoided the difficulties of calculating 0 K EOS of materials. By applying it to aluminum and copper, the results were well consistent with experimental data. And the calculated onset of melting on the Hugoniot curves of aluminum and copper were (125.5 GPa, 4 705 K) and (231 GPa, 5 369 K), respectively, in good agreement with the presented experimental data of aluminum and copper.
