摘要

引力波信号的探测再次验证了100多年前爱因斯坦创立的广义相对论理论。本文说明了引力波速与真空光速相等的原因在于广义光速不变原理;速度差别原因在于介质的效应。本文由电磁学真空和介质理论的关系总结出来处理介质背景问题的方法,把真空中波速替换为介质中波速,建立相关的介质理论。我们借此修改了爱因斯坦场方程,得到了引力波波动方程,讨论引力波波速不等于真空中光速的情况。基于修改的爱因斯坦场方程,给出了一些宇宙学推论。理论对弗雷德曼方程有微小的修正。
        Detection of signal of gravitational wave verified the theory of General Relativity which was created by Einstein 100 years ago.In this paper we showed that the reason for equivalence between velocity of light in the vacuum and gravitational waves is general principle of universal velocity of light.and the inequivalence is an effect of the media.We find a systematic way to deal with the theory in the media background.The velocity in the vacuum is replaced by the velocity in the media,then the theory of the media can be constructed.We use the theory modified Einstein field equation,and got the wave equation of gravitation.Also we discussed the situation that the velocity of light is not equal to the velocity of gravitation.Based on the modified theory of Einstein field equation,we talked the modification of the Friedmann equation.
