船电设备电磁工程学的有限元法研究

论及船舶电工设备电磁工程学的基础理论——电磁场数值分析方法。提出了有限元原理的一种新的证明方法，其命题为：在磁阻连续或间断的区域中，磁场边值问题（非线性Ｐｏｉｓｓｏｎ方程）总是等价于条件变分问题（能量泛函取极小值）。

Research on Finite Element Method in Electromagnetic Engineering of Ship Electrical Equipment

This paper is the achievement in the numerical analysis of the electromagnetic fields which is the fundamental theory and basic method in the electromagnetic engineering of ship electrical equipment, and a report on the new proof of FEM. We shall prove the proposition that the correct solution of nonlinear poisson equation is always on an equality with minimizing the nonlinear energy function in the region of different magnetic resistance.
