由此得出结论，在非线性磁场计算中：采用迭代法的情况下，在各迭代循环之间进行磁导率修正时，一个欠松弛迭代过程是必需的；对永磁体中的等效电流修正时可以不作欠松弛迭代；在纯铁的磁化曲线上指定某一个固定的磁感应强度为磁饱和值，会使得插值求出的磁导率在该磁饱和值附近有一突变,这一突变对计算结果中磁场分布变化的光滑性稍有影响。在微波管磁系统设计中，由于微波管磁路比较复杂，作者认为磁体的工作点并不能很好地反映磁体的工作状态，而采用平均磁能积为衡量磁体工作状态的标准更加符合微波管磁系统的实际情况；要表示磁系统设计好坏的程度，则用磁能利用的效率为标准更好。 | | 6. | In order to improve oil displacement efficiency of infusing agents and precisely to predict the three dimensional distribution about residual oil , taking the sand body of p 2 individual meandering river - channel in putaohuareservior of daqing oilfield as an example , by analyzing the thin interbeds and vertical permeability discrepancy , this paper brings forward the space configuration of the thin interbeds in single sand body , the vertical permeability distribution and gravitational differentiation which control the distribution of residual oil and the vertical multisection model of displacement efficiency in the condition of excluding exploitation factors and identical single sand - body ,
