摘要
在测量超声波在均匀媒质中传播速度的基础上,利用时差法进行数据测量,并利用Origin软件对数据进行线性拟合得出在复合介质中超声波的声速.
Based on the measurement of ultrasonic propagation velocity in a homogeneous medi‐um ,the data were measured using time‐difference method ,the velocity of ultrasonic wave in compos‐ite medium was obtained using Origin software to fit the data linearly ,and the results were discussed and analyzed .
