大自然奇妙而又神秘的对称美普遍存在于各种物理现象、物理过程和物理规律中.从某种意义上讲,物理学的每一次重大突破都有美学思想在其中的体现.用对称性思想去审题,从对称性角度去分析和解决问题,将给人耳目一新的感觉.本文通过对带电粒子在电磁场中的运动问题的分析,体会其中的美学思想和对称美的感受.一、一片绿叶例1:如图1所示,在xOy平面内有很多质量 The marvelous and mysterious symmetry of nature in nature is commonly found in various physical phenomena, physical processes and laws of physics, and in a sense, every major breakthrough in physics embodies aesthetic ideas in it. Thought to examine questions, from the symmetry point of view to analyze and solve the problem, will give a refreshing feeling.This article through the analysis of the movement of charged particles in the electromagnetic field, to understand the aesthetic ideas and symmetry of the United States feel. 1: As shown in Figure 1, there is a lot of mass in the xOy plane
