摘要
对称性是物质世界的普遍规律,而在电磁学中,对称性更是有着重要应用。对称性不仅是各种电磁规律的本质体现,也是解决各类电磁学问题的有力工具。当系统在某种对称操作下状态不发生改变时,应用对称性往往能巧妙地发现其中隐藏的规律。
Symmetry is the universal law in physical world, and it plays an important part in electromagnetics. Symmetry is not only the reflection for all kinds of electromagnetic laws in nature, but also the effective tool for solving all electro- magnetic problems. While no changes occurred in the system under a symmetrical operating state, applying the symmetry rule can ingeniously find the hidden rules.
