Study on Characteristics of Time and Space

Ning Zhang

Abstract

Gravitational field is a kind of vector field,and the description of general relativity to gravitational force problem is very effective.This paper deals with the equivalence principle and the principle of general covariance in general relativity,discusses Einstein’s gravitational field equations,researches on the principle of relativity,time dilation,contraction of length in gravitational field.
