摘　　要：超声学是一门应用性和边缘性很强的学科，可以超声为工具，来检验、测量或控制各种非声学量及其变化的，超声测量在国防、工农业生产、医学、基础研究等领域有着重要的应用。本文基于脉冲回波法的超声原理，采用51单片机设计一种常用的测距仪。Ultrasonics, an applied and marginalized subject, can be used as a tool to test, measure or control a variety of acoustics measurements and its changes. Ultrasonic measurement plays an important role in in the defense, industrial and agricultural production, medicine and basic research. Based on the principle of ultrasonic pulse echo method, a common ultrasonic range finder is designed with the use of 51 single -chip microcomputer.
