摘要
超声波是材料无损评定的主要手段之一，本文介绍了采用相位谱的超声波速度测量技术，并给出了声频散材料──石墨的实验结果。
Ultrasonic is an important tool for nondestructive evaluation of materials. This paper introduces a phase spectrum method for determination of ultrasonic wave velocity. Experimental results are presented to demonstrate the effectiveness of the technique for the ultrasonictesting in dispersive materials such as Graphite,
