摘要
主要介绍用利用声速测速仪、双帧示波器等仪器 ,通过声、电信号的转换 ,精确测量声波传播中的相位差、波长。
This paper introduces the method of using the devices of sound speed, double beam oscillograph to measure precisely physical quantities of propagation of phase difference , wavelength, wave speed through the transformation of sound and electic signals.
