广义相对论中的时空度量和光速

Space-Time Measures in General Relativity and Velocity of Light

爱因斯坦引力几何化的思想是解决引力本质问题的关键,从而广义相对论中的时空度量问题就是实现这一思想的核心问题;关于广义相对论中是否存在有如狭义相对论那样的"光速不变"问题,往往有着不同的说法,在此给出了说明.

The idea of Einstain＇ s gravitation geometricization is the key to solve the problem about the nature of gravitation, and space - time measures in general relativity is the core to accomplish the idea. There are different views on whether the fact that the velocity of light is constant exists in general relativity as it does in special relativity, which this paper discusses about.
