度规张量是广义相对论的核心,要想真正理解广义相对论,必须首先理解度规张量.系统论述了度规张量的几何意义和物理意义以及它的一些重要特性,利用度规张量的意义和等效原理可以快速确定史瓦西度规.
Metric tensor is the core of the general theory of relativity.To truly understand the general theory of relativity,we must understand the meaning of metric tensor.The system discussed the geometric and physical meaning and some of its important characteristics of the metric tensor.Using the significance of metric tensor and principle of equivalent,we can quickly determines the Schwarzschild's metric tensor.
