固体材料拉伸波速的共振法测量

文章系统论述了利用弯曲共振和纵向共振两种方式测量拉伸波速的方法，作者改进了传统的纵向共振测试装置，指出了两种方式各自的适用性．在理论上纵向共振方法更为严谨，且误差来源较少，从而具有较高测量精度，实验上测量操作更为方便．

RESONANCE MEASUREMENT METHODS FOR EXTENSIONAL WAVE VELOCITIES IS SOLID MATERIALS

This article made a systematic study for measuring methods of extensional wave velocities using flexural and longitudinal resonance vibrations, and improved traditional measuring equipment arrangement of longitudinal resonance vibration. In this paper, the suitable range of two measuring methods was pointed out. Theoretically, longitudinal resonance vibration is stricter than flexural resonance vibration measuring, and there exists fewer sources of error in longitudinal resonance vibration measuring, it brings a satisfy measuring result with high precision. The measuring operations of longitudinal resonance vibration are flexible.
