| 摘 要： | 讨论了驻波法测空气中声速的实验,分别用相位比较法和李萨如图法来确定超声波波长.在不同温度条件下测量了声速并与理论值进行比较,实验结果显示测量温度接近室温时实验值与理论值基本一致,测量温度与室温相差较大时实验值与理论值偏差较大.

| Abstract: | Measuring sound velocity in the air using stationary wave method is discussed in this paper,phase comparison method and Lissajous figure method both could determine the wave length of ultrasonic wave.Sound velocities at different temperatures are measured and compared with theoretical value,the experimental results obtained at room temperature are in good accordance with the theoretical results,but when temperature deviates from room temperature significant discrepancy occurs. |

| Keywords: | sound velocity temperature stationary wave method ultrasonic wave |
