【摘要】 本文首先回顾了电磁场理论基础中的矢量微分算子,然后列举了电磁理论中的一些相关对称性,并重点分析了M axwell方程组的对称性,在假定磁单极子存在的条件下,推导出含磁单极子的具有更高数学对称性的M axwell方程组;最后给出了一个用对称性原理来讨论磁偶极场的一个方法.更多还原

【Abstract】 After brief review of the vector differential symbol in electric-magnetic field theory,this paper clarifies the symmetry principle in the electromagnetism and focuses analyzes the symmetrical balance in Maxwell’s equations.Assuming that the Dirac monopole is exist,we will get some higher symmetry in Maxwell’equations;Finally,the application of the symmetry in solving the problems was also presented.更多还原
