摘要
驻波法测量空气中的声速实验中 ,由于反射波的振幅小于正向波的振幅 ,合成后形成的是非完全驻波 ,实际上 ,这是一个驻波与行波的叠加。
The partial standing wave exits in the experiment of determining velocity of sound by standing wave method because the amplitude of a reflected wave is less than that of a forward wave.Actually,it is a superimposure of standing wave and a traveling wave.
