| 摘 要： | 介绍了压电陶瓷换能器产生和接收超声波的工作原理，当输入电压的频率为谐振频率时，超声波在介质中产生的驻波最强。若管道中出现泄漏，接收换能器的电压立即发生变化，可以根据这种变化发现泄漏，进而按拟合曲线或方程计算出管道泄漏的位置。

| Abstract: | The principle of producing and receiving ultrasonic wave with the piezoelectric ceramics transducer is introduced. Standing wave is strongest when voltage frequency is resonance. If there is a leak in the pipeline, the voltage of receiving transducer changes immediately. The leak position can be located with curve or formula. |
