摘要: 利用超声脉冲重合法测量了多晶Al、Cu、Ta的弹性模量及其压力的偏导数。由Birch-Murnaghan物态方程得到的三种金属的等温线与冲击波等温线作了比较。Abstract: By use of the ultrasonic pulse echo overlap technique, the elastic moduli of isotropic polycrystalline Al, Cu and Ta, and their pressure derivatives have been determined. The isotherms for these metals, calculated from Birch-Murnaghan equation of state are also compared with the shock wave isotherms.
