摘　　要：确定铁磁材料的磁滞回线的绘制属于最小二乘法问题,并确定用分段三次多项式来拟合.给出三次多项式拟合,以及在求解过程中解法方程的方法,并给出了具体算法.The paper makes certain that rendering the magnetic hysteresis loop of the polynomial fitting ferromagnetic material belongs to linearly two minimum multiplication problem, and makes sure to use the piecewise polynomial ofto fit. The paper introduces the fitting three times polynomial and the method of reducing the equation, gives the concrete way of calculating.
