摘　　要：超声波在传播过程中,反射波的时间差与被测量物体的厚度成正比。采用超声波反射波脉冲信号的时间差,来检测工件涂层后内层表面的加工质量,并根据扫描工件表面的测量数据,在计算机上进行三维成像。因此,采用超声波反射波脉冲信号可以完成工件内层表面加工的测量与监测。In the dissemination process of ultrasonic, the difference of time between two signals of echoes would be direct proportion to the thickness of product. The quantity of product coat was measured by time diflevence of reflection pulse in the measurement device. And the imaging in three-dimensional was done on a computer, according to the measurement data by scanning the surface of product. Thus it was completed the measurement and monitor.
