所谓对称法,就是应用对称性去求解某些具体的物理问题的思维方法.物理中对称现象比比皆是,对称表现为物理过程在时间上和空间上的对称性、物理量在分布上的对称性.采用对称法可以避免繁琐的物理分析和数学推导,而直接利用事物之间的对称关系得出结论;不仅使解决问题的步骤变得简洁,而且对事物的结构有更深刻的理解,直接抓住问题的实质,就可出奇制胜,快速简便地求解问题.笔者结合几个具体实例,谈谈对称法在高中物 The so-called symmetry method is to use symmetry to solve some specific physical problems of thinking method.Physics symmetry phenomena abound, the symmetry of the physical process in time and space symmetry, the physical distribution of the symmetry The symmetry method avoids tedious physical analysis and mathematical derivation, and directly draws conclusions from the symmetrical relations between things; it not only simplifies the steps to solve the problem but also has a deeper understanding of the structure of things, and directly grasps Live the essence of the problem, you can surprisingly win, quick and easy solution to the problem. I combine a few specific examples to talk about symmetry in high school
