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。Expanding the system ' s hamiltonian to a real symmetric matrix in an appropriate orthogonal basis vector and then diagonalizing it, we get the energy spectrum of the system and calculate the energy level spacing distribution function and the spectral rigidity. then we study the statistical character of the energy spectrum under the changing of magnetic field intension and find that the system ' s motion transfers from regular to chaos gradually

這是因為當結構陶瓷中裂紋尖端的應力作用在彌散於基體內的鐵磁體二相粒子上時,鐵磁粒子不僅在裂紋尖端周圍產生的非彈性區域使復合材料的韌性提高;而且還能利用鐵磁材料在外應力作用下自發磁化強度發生變化的性質,通過測量復合材料在應力作用下磁場強度的變化,探測出結構陶瓷中的應力分佈情況。The particle size of the product is about 16 nm with perfect crystal structure. the product exhibits superparamagnetism and strong magnetic responsivity, the saturation magnetization being 55. 4emu / g and the magnetic susceptibility being 8. 28 10 - 3emu / oe. the particle size distribution is homogeneous with good dispersion. 2
