起声波接触阻抗原理是超声波硬度检验法的基本原理,该方法可以在试件尚处于加载时测量其压痕面积,从而提高测量精确度。
The principle of acoustic contact impedance is the basic principle of the ultrasonic hardness test. This method can measure the indentation area of the specimen while the specimen is still being loaded, thereby improving the measurement accuracy.
