摘要

近来有些文章断言,在一个惯性参考系里能量守恒的物理系统,在别的参考系看来能量也一定守恒.实际上这些作者混淆了物理方程式的协变性和相对性原理.本文将澄清这一误解.

Abstract

Some authors confirm that the energy of a physical system conserves in an inertial frame of referencemust do so in any other frames. Actually they have confused the covariance of equations with the principle of relativity. The present article attempts to clear up this misunderstanding.
