对称性与对称方法

Symmetry and Symmetrical Method

从时空对称性质出发,讨论守恒定律与对称性的关系,介绍物理学中常用的几种对称方法,论述对称性和对称方法在物理学研究中的重要意义.

In this paper,in the light of symmetrical properties of space-time,the relation between symmetry and conservation law is discussed,a few symmetrical methods used frequently in physics are introduced. Moreover,the significance of symmetry and symmetrical method in the physics research is expounded.
