对称性在物理中的应用

The Application of Symmetry in Physics

对称性思想是物理学的基本思想之一,在整个物理学的发展中起着举足轻重的作用。本文从大学物理的基础知识点入手,来探讨对称性思想在力学,特别是刚体力学中的具体体现形式和应用,以及在电磁学领域麦克斯韦方程组所体现出来的优美对称性,和用麦克斯韦方程组来解决问题时所用到的对称性思想。通过对物理不同分支对称性思想的研究,来探究对称性思想的重要意义。

The idea of symmetry is one of the basic ideas of physics,and it plays a pivotal role in the development of the whole physics;this paper starts with the basic knowledge of university physics,and discusses the specific application of the idea of symmetry in mechanics,especially rigid body mechanics.It embodies the form and application,as well as the beautiful symmetry embodied by Maxwell's equations in the field of electromagnetism,and the symmetry ideas used when using Maxwell's equations to solve problems.Through the study of symmetry ideas in different branches of physics,to explore The importance of the idea of symmetry.
