摘　　要：根据声波在两个换能器多次反射和声波在空气中的衰减,研究共振干涉法测量声速实验中的信号发生器输出信号随接收器到发送器间距离的变化,测出声波的波长,以及声速.According to the two acoustic transducer and the multiple reflections of acoustic attenuation in the air research resonance interferometry experiments measuring speed of sound output signal of the receiver with the receiver to the transmitter changes the distance between, Measured the wavelength of sound waves, as well as the speed of sound.

关 键 词：声速测量 驻波 换能器
