这些积分中的第一个被看成是对数形式，而第二个被看成是反正切形式。
The first of these integrals is seen to be a logarithmic form and the second the inverse tangent form.
相对于修正反正切函数模型，能更为合理地预测铁芯深度饱和后的特性。
Compared with modified arc tangent function model, it is more reasonable for predicting the slope of the characteristic of the core at deep saturation.
