陈光平等给出了多普勒效应的一种统一形式，但当波速低于光速时，其涉及第三方参考系———介质系的观测，故而 使用起来颇为不便. 本文探讨了一种多普勒效应的简洁统一形式并给出证明，同时给出了这种简洁统一形式在光速和远小于 光速时的情况. 这种简洁统一形式不仅不会涉及介质系，而且具有对称的物理美. 并且，通过对公式本身的作图分析，得知多 普勒效应中的相对论效应是随着速度的增加而逐渐显现的，并不是与经典多普勒效应的简单叠加.

A unified form of Doppler effect was given in a reference，but it involves a third-party reference system，i. e. ，the media observation system when the velocity of wave is lower than the speed of light，so，it is not convenient to use. In this paper，a simple and unified form of Doppler effect is discussed and the proof is given.This kind of simple and unified form is given at the situation of the speed of light and far less than the speed of light. This concise form does not involve the media observation system，but also has the beauty of symmetry. And through the analysis of the formula，we get that the relativistic effect appears gradually with the increase of velocity，and is not a simple superposition of the classical Doppler effect.
