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。
By use of the ultrasonic pulse echo overlap technique, the elastic moduli of isotropic polycrystalline AI.Cu and Ta.and their pressure derivatives have been determined. The isotherms for these three metals, calculated from Birch-Murnaghan e-quation of state are also compared with the shock wave isotherms.
