摘要
本文给出了在涡流区、场源区采用矢量磁位Ａ、标量电位φ，而在非导电区（气隙）采用标量磁位Ω，来求解三维涡流问题的分区变分原理·通过泛函变分能得到不同区域内的控制方程，自然边界条件，以及满足电磁连续性要求的区域界面连续条件·
In this paper, a divided region variational principle to solve 3_D eddy current problems was given. It adopts the magnetic vector potential A and the electric scalar potential φ in the eddy current rgeions and the source regions, and the magnetic scalar potential Ω in the non_conducting regions (air gap). Using variation of the functional, all governing equations in various regions, the natural boundary conditions and the interface continuity conditions which satisfy electromagnetic continuity are obtained.
