摘要
本文将扼要介绍物理学中对称性的分类及其特征，说明对称性破缺与一物理系统从无序到有序的相变过程间的关系。
In this paper we discuss the classification and characteristics of symmetry in physics,analyze in detail the connection between broken symmetry and phase transition as a process from disorder to order in physical systems,and discuss the prerequisite conditions to the appearance of broken symmetry.
