时空对称性与力学守恒定律
摘要
本文介绍了惯性系的时空观描述
利用惯性系中的时空性质与拉格朗日方程推证了力学中的三大守恒定律。
Abstract
In this paper
We give the description of inertial system by presenting the properties of space - time in it. Based on the use of the properties of space - time and Lagrange’ s equation
we obtain the three mechanical conservation laws.
