摘要
声速测量是大学物理实验中的一个经典实验,常用的方法有共振干涉法、相位比较法、时差法等。在此基础上拓展了相位直观比较法、信号叠加法,帮助学生更好地理解声速测量原理。同时基于AI技术,探索研究了盐水温度和浓度对声速的影响,助力于海水中声速的研究,并为AI赋能物理实验教学提供思路。
Sound velocity measurement is a classic experiment in university physics experiments,and commonly used methods include resonance interferometry method,phase comparison method,and time difference method.On this basis,extends the phase intuitive comparison method and signal superposition method to help students better understand the principle of sound velocity measurement.At the same time,also explores the impact of saltwater temperature and concentration on sound velocity based on AI technology,which contributes to the study of sound velocity in seawater and provides ideas for empowering physics experimental teaching with AI.
