摘　　要：建立了利用冲击波实验测量得的Hugon iot参数和Morse势来确定金属铁的高压状态方程的方法,并用此方法计算金属铁的高压状态方程,特别是铁的结合能、热压和温度,所得结果比其它模型的计算结果与实验结论更为一致.Based on Morse potential and Hugoniot parameters measured by the shock wave experiment, a new method has been introduced to determine the hot-pressure equation of state for metallic iron. This method is used to calculate the hot-pressure equation of state, the bound energy, the hot-pressure and the temperature. The calculated results are more consistent with the experimental values than that of other models.
