声波多普勒效应的相对性

On the Relativity of Sound Wave Doppler Effect

讨论了物理学教学中有关声波多普勒效应的相对性问题。按照相对运动的原理，对于不同参照系的声波多普勒效应，其产生过程的解释也不相同。

The relativity of sound wave Doppler effect that is present in the course of physics has been discussed.According to the priciple of the relativity of motion, the different processes of producing sound wave Doppler effect have been explained from different angles of reference system,and preliminarily compared the Doppler effect of sound wave with that of light wave.
