电场及磁场的对称性分析

Symmetry analysis on electric field and magnetic field

利用对称性的概念和矢量场的对称性分析计算方法,讨论了某些具有对称性的带电体场及载流体场的计算,特别是对其中的重点和难点问题进行了详细的分析和论证。对称性方法可以使具有对称性的场的计算问题的物理图像清晰,简化计算,易于理解。

The fields of some of the charged objects and current carrying objects with certain symmetries are cal- culated using the symmetry concept and symmetry analysis method, and especially, the key points in dealing with such problems are investigated in detail. In dealing with these problems, symmetry analysis method can make the physical pictures more clear, the calculations more simple, and the understanding much easier.
