| 摘 要： | 将固体间界面层模拟为固体或流体薄层，本文讨论了界面层对斜入射纵波和横波的反射和透射，测量了垂直入射纵波的反射系统随声波频率的两铜块之间水界面层厚度的变化。理论和实验结果基本符合。

| Abstract: | By simulating the interface between two solids as a thin solid or liquid layer, we discussed the reflection and transmission coefficients of sound waves obliquely incident on the interface. We also measured the ultrasonic reflection coefficients of longitudinal wave normally incident on water layers with different thickness between two cooper blocks. The theoretical and experimental results are in good agreement. |
