含非线性磁介质材料恒定磁场的差分离散

The different discrete of constant magnetic fields in Non-linear magnetic medium material

给出了含非线性磁介质恒定磁场中用积分泊松方程的差分离散 ,该方法把求解非线性准泊松方程边值问题转化成求解线性代数方程组 ,在变压器、电机内电磁场的分析与计算中具有广泛的应用。

This paper introduces the differeat discrete method with integral poisen equation in which solving the boundary value problems of nonlinear quasi poisen equation can be transformed into linear algebraic equations in constant magnetic fields,which contain nonlinear magnetic medium material.It can be widely applied to analysis and calculation of the electromagnetic field of transformer and motor.
