| 摘 要： | 通过引入“积分第三类边界条件”．提出以磁场强度Ｈ为变量，计算二维多连通域涡流场时．对多连通域边界条件的新的处理方法及其相应的有限元方程．该法使计算区域仅局限于涡流区内，内存占用量省．计算精度高，并可实现当涡流区导体中存在无限窄裂缝情况下的有限元模拟．

| Abstract: | A FEM is applied to solve the field problems with this kind of boundry condition, By the introduction of this boundry condition, there is only one unknown node left per time, and only the conducting region needs to be considered for the multi-connected field problems. |

| Keywords: | eddy current field FEM boundary condition multi-connected region |
