速度相加定理与光速不变原理相容性探析

Exploring the Compatibility of the Velocity Addition Ruleand the Universal Speed of Light

在低速近似(v<<C)情况下,相对论速度相加定理便退化为经典的速度相加定理.研究问题的速度所处的范围为:低速,选经典速度相加定理;高速,选相对论速度相加定理;相对论速度相加定理与光速不变原理是相容的,真空中光速大小与惯性系的选择无关.

In the case of low-speed approximation(v<<C),the relativistic velocity addition theorem degenerates into the classical velocity addition theorem.When the speed of the problem is at a low speed,the classical velocity addition theorem is chosen;when the speed of the problem is at a high speed,the relativistic velocity addition theorem is chosen.The relativistic velocity addition rule is compatible with the universal speed of light.The speed of light in vacuum is independent of the choice of inertial frame.
