摘要
本文利用时空坐标变换、波速变换及傅里叶变换的方法,导出了弹性波和电磁波多普勒效应的普遍公式。讨论了弹性波多普勒效应的叠加性质,并指出相对论的时间膨胀和长度收缩对弹性波多普勒效应的影响。
By utilizing the transformation of time—space coordinates, the transformation of wave velocity and the Fourier transformation, this paper derivates the general expressions of Doppler effects of electromagnetic wave and elastic wave. The superposition property of elastic wave′s Doppler effect and the influence of relativistic time dilation and length contraction on elastic wave′s Doppler effect are also discussed.
