摘要: “驻波法”和“相位法”是声速测量实验中常用的两种方法.文章针对声速测量实验采用“驻波法”和“相位法”的测量原理、测量方法和实验数据处理等几个方面进行了较全面的比较分析与探讨,这对大学物理实验教学具有一定的实际参考意义. 关键词:声速; 测量; 驻波法; 相位法Abstract: “Standing wave method” and “phase method” are two commonly-used methods in the experiment of sound velocity measurement. The paper gives a comparison and analysis of the two methods in terns of the measurement principle, measurement method and experimental data processing in the experiment of sound velocity measurement. It is of some practical reference value for college physics experiment teaching.
