| 摘 要： | 共振干涉法和相位比较法是大学物理实验中常用的测量声速的方法,但工程应用很广泛的时差法测量声速却很少在大学物理实验内容中涉及。在文中实验用时差法测量声速的实验结果和理论值相符较好,并对实验结果进行讨论和分析。

| Abstract: | The resonance coherent method and phase comparative method are generally used for measuring the sound velocity in university physical experiment.But few experiments concern time difference method that is abroad in ultrasonic wave industry application.In experiment the results that come from time difference method act in good accord with theoretical results.And the results are analyzed and discussed. |
