摘　　要：驻波法和相位法是大学物理实验中用来测声速的两种实验方法,通过理论分析以及实验所得的数据对两种方法测声速的准确度问题进行了研究,统计得出驻波法的实验误差大于相位法。Standing wave method and phase method are two kinds of experimental methods for measuring sound velocity in university physics experiments.The accuracy of measuring sound velocity by these two methods is studied through theoretical analysis and experimental data,and the experimental error of standing wave method is greater than that of phase method.

关 键 词：驻波法 相位法 声速测量 误差
