| 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,但是时差法很少被涉及。所设计的仪器在原有仪器功能的基础上增加时差法测量声速的内容,因为利用了单片机技术,在仪器成本没有增加的情况下,给该实验增加了一种实际常用的测量方法,并且数据测量结果与理论值符合得相当好。

| Abstract: | The resonance coherent method and phase comparative method are generally used for measuring the sound velocity in university physical experiment. But few measuring instruments use time difference method. In our designing instrument,the time difference method is used under keeping the old functions and the cost of the instrument is almost the same as the old because the single chip processor technology is used. The measuring result accords well with the calculating data in this experiment. |
