本文尝试用包层金属缓冲棒聚焦超声脉冲回波技术探测650°C锌液中悬浮的杂质颗粒。聚焦的超声波由制作在缓冲杆端部的球形声透镜产生。在10 MHz下进行了实验。实验结果表明，利用所设计的聚焦缓冲棒，可以对锌液中的杂质颗粒进行检测。
An attempt for detecting impurity particles suspended in molten zinc at 650°C has been made using a focused ultrasonic pulse-echo technique with a clad metallic buffer rod. The focused ultrasonic waves are generated by a spherical acoustic lens which is fabricated at the end of the buffer rod. An experiment is carried out at 10 MHz. The result shows that impurity particles in molten zinc are detectable by using the presented focusing buffer rod.
