无旋场

本文讨论了谐振腔中亥姆霍兹定理的合理形式，即谐振腔内的电场怎样分解为相互正交的电旋量场和电无旋场的形式。

The rational form of Helmholtz theorem in resonant cavity is discussed .

结果表明，不论是无旋场还是有旋场，基于互补途径的误差估计是可行的。

It is shown that both local and global errors decrease as the number of nodes are increased , so the error estimates based on the complementary variational approach is feasible .
