由此得出結論,在非線性磁場計算中:採用迭代法的情況下,在各迭代循環之間進行磁導率修正時,一個欠鬆弛迭代過程是必需的;對永磁體中的等效電流修正時可以不作欠鬆弛迭代;在純鐵的磁化曲線上指定某一個固定的磁感應強度為磁飽和值,會使得插值求出的磁導率在該磁飽和值附近有一突變,這一突變對計算結果中磁場分佈變化的光滑性稍有影響。在微波管磁系統設計中,由於微波管磁路比較復雜,作者認為磁體的工作點並不能很好地反映磁體的工作狀態,而採用平均磁能積為衡量磁體工作狀態的標準更加符合微波管磁系統的實際情況;要表示磁系統設計好壞的程度,則用磁能利用的效率為標準更好。Because of the importance of the industry, the paper is valuable in engineering. the paper also discusses multi - field, multi - phase, multi - state and computer technology, so the paper is also valuable in study. in chapter 1, the background, the history and the study status of model of " flow of fluid - solid material along a curved line by stretch " are provided
