| 摘 要： | 电磁领域研究中,经常会遇到能量关系中的无耗对称,源点和场点之间的互易对称和几何方面的镜像对称等等.本文采用引入对称算子统一地描述各种电磁对称.特别指出:电磁互易对称即Weyl在力学领域中提出著名的辛对称.文中还深入研究了二次型对称形式和一次型对称形式.

| Abstract: | Symmetry is generalized property in electromagnetic research,such as the lossless symmetry in the energy relation,the reciprocal symmetry between source point and field point and mirror symmetry on geometric.A symmetric operator is introduced to uniformly describe various electromagnetic symmetries.The electromagnetic reciprocal symmetry is a kind of symplectic symmetry proposed by Weyl in the mechanics region.Symmetry of quadric form and dispensable mould are also analyzed. |
