电磁波的相位不变性的一种简单证明和相对论性的多普勒频移公式

A Simple Proof of Phrase Constancy of Electromagneticwaves and Doppler Frequency Shift Formula of Relativistic

作者在该文中从世界空间的四维坐标和四维波矢量出发，证明了电磁波的相位不变性。此方法数学形式简洁，物理意义突出。进而从相位的不变性结合洛仑兹坐标变换式得到相对论性多普勒频移公式。

This article, on the basis of four dimensional coordinates and four dimensional wave vectors of world space, proves the phrase constancy of electromagnetic waves.This method has been brief in mathematics andthe meaning in physics is clear. On combining the phrase constancy of electromagneticwaves with the Lorents coordinates transform author obtains Doppler frequency shift formula of relativistic.
