| 摘 要： | 使用普通的超声换能器，用高频率换能器作发射端，低频率换能器作接收端，通过互相关谱分析，可以得到反射声波的到时，从而计算得到混凝土的厚度。实验表明，本方法对混凝土厚度的测量具有较高的精度和可靠性。

| Abstract: | The arrival time of reflected acoustic wave is received with cross correlation spectrum using general ultrasonic transductor through took high frequency transductor as a emissive end, and low one as a receive end. The experiment indicats that this method has higher accuracy and reliability for the detection of concrete thickness. |
