摘要
本文讨论描述软磁铁物质中强脉冲磁场的一种非线性方程组 ,给出了这个方程组存在二个解和四个解的条件 ,并给出了求解此方程组的计算方法 .
A simple relative differential permeability model with two exponential terms is discussed in this paper. We give out the conditions under which the system has two or four positive solutions. The schema to get numerical solutions is give.
