摘要
针对现有的声多普勒效应实验装置中存在的问题,设计并制作了摆动式声多普勒效应实验仪.该仪器能够分别进行声源运动和观察者运动的声多普勒效应实验,且可定量分析频偏和测量速度.本文详细介绍了该仪器的原理、构造、特点和实验过程,并对实验结果进行了较为全面的分析.
Aiming at the deficiency of existing Doppler effect demonstration instrument, the wiggling-type ultrasonic Doppler effect experiment instrument is designed. The instrument can demonstrate ultrasonic Doppler effect, analyze the frequency deviation and measure the velocity. This paper details the working principles, the structure, and the features of this wiggling-type ultrasonic Doppler effect instrument and the process of experiment. It also makes a comprehensive analysis to the experimental results.
