摘要
Abstract
A system is developed for measuring the propagation time of ultrasonic wave in normal stress measurement with critically refracted longitudinal wave( LCR wave), constitution and operating principle about the system is presented. Linear frequency modulated continuous wave(LFMCW) is adopted in the system to stimulate continuously LCR wave based on the way to measure the propagation time with LFMCW. The system runs successfully and the result shows that it has the ability to measure the propagation time.关键词
