| 摘 要： | 给出了利用Hugoniot参数计算材料冷能、冷压和结合能的一种新方法，对52种纯元素单质固体材料的计算表明，该方法的计算误差较小，对计算碱金属等外层电子数较少的材料效果尤佳。利用文中给出的冷能、冷压公式，计算出的铝、铜、银和锌等材料的冲击绝热线与实验数据符合得非常好。

| Abstract: | A new method for calculating cold energy,cold pressure and cohesive energy was poroposed.Cohesive energy calculations for 52 metals show that the calculated results using this method are consistent with the experimental data,especially for alkali metals.Comparison of Hugoniot curves calculated based on cold energy and cold pressure with the experimental Hugoniot data of aluminum,copper,zinc and silver,shows that this method can be applied to calculate cold energy and cold pressure of solid materials. |

| Keywords: | cold energy cold pressure cohesive energy Hugoniot parameter |
