关于多普勒效应的叠加性，论文《弹性波相位不变性与平面弹性波变换》中指出：在相对论情形，多普勒效应不具有叠加性.本文不同意这一观点，通过澄清频率变换与多普勒效应的关系，引入效应因子和叠加性的定义，分别由相位不变原理和四维波矢的洛伦兹变换分析这一问题.所得结论为：相对论情形的多普勒效应仍具有叠加性.

 Regarding the superimposition of the Doppler effect, the article “Phase invariance of elastic wave and transformation of plane elastic wave” states that in the case of relativity, the Doppler effect does not have superimposition. This view is not agreed in this article, through clarifying the relationship between the frequency transformation and the Doppler effect, and introducing the definitions of effect factor and superimposition properties, then analyzes this problem by using the phase invariant principle and the four-dimensional wave vector transformation, respectively. The conclusion is that the Doppler effect in the case of relativity is still superimposed.
