摘　　要：多普勒效应是声波传播过程中一个重要的现象.对此类问题的研究一般仅限于声源和观测者在同一直线上运动的情形.本文利用3种不同的方法,对任意方向的多普勒效应作一探讨,方法简单,便于理解,根据由此得出的结论分别讨论,还可得出各种情形下与同一直线上多普勒效应相一致的结果和公式.Doppler effect is an important phenomenon in propagation process of sound wave. The study on this problem mostly confined to one situation-while the sound source and observer move on a same straight line. This article discusses the Doppler effect on any direction by using three different methods which are simply and easy to understand. According to the conclusion discussed,we can obtain the formulas and results which are consistent with the Doppler effect on a same straight line in various conditions.
