物理中存在许多优美的对称性。利用对称性解决物理问题的解题法叫对称性解法。该解法没有冗长的数学推导和繁杂的计算,能快捷、准确的解决问题,它能培养学生敏捷的思路,锻炼学生用简单明了的道理去说明和理解深刻的物理本质的能力,使问题显现出美妙而富有对称性的物理本质来。 There are many beautiful symmetries in physics. The problem solving method that uses symmetry to solve physical problems is called symmetry solution. The solution does not have lengthy mathematical derivation and complicated calculations. It can solve problems quickly and accurately. It can train students’ agile ideas and train students to use simple and straightforward principles to explain and understand the profound physical essence of the ability to make problems appear. Wonderful and symmetrical physical nature.
