| 摘 要： | 将铝、铁、铜等七种材料弹性声速的实测数据进行分析处理发现，其弹性声速随压力的变化均可以用一下关系：ln c=A0+A1ln p+A2ln2p，很好的拟合。拟合结果与实测值的相对误差小于5%。

| Abstract: | After treating analytically the measured elastic sound speed c of seven materials, including aluminum, iron, copper and so on, at high pressures, it is shown that the change of the elastic sound speed with pressures may be described ashere, A0,A1,A2, are material constants, p is the pressure. The relative error between the fitting data and the measured data is less than 5 %. |
