The two sunspots of a pair have different polarities, one would be a magnetic north and the other is a magnetic south. thus, we believe that there are magnetic field lines joining the two sunspots of a pair. the strong magnetic field locks the gas of the photosphere in places and inhibits the hotter gas below to rise at the sunspots
黑子經常成雙成對出現,每對皆由極性相反的黑子組成,若一個為磁北,另一個必為磁南,由此我們估計每對黑子皆由磁力線所連系,強大的磁場牽制著光球層上的氣體,並阻止了下層較熾熱的氣體上升至黑子范圍,結果黑子比太陽表面其他地方溫度較低。By successful solution of non - linear magnetic fields and revision of the program, we can reach following conclusions : in the computation of nonlinear magnetic fields, if iteration method is used, under - relaxation is necessary when amending the permeability distribution in soft magnetic materials ; and when < wp = 5 > calculating the equivalent current density in permanent magnets, under - relaxation is not a necessity ; when searching for permeability values by interpolation method on the demagnetization curve of soft magnetic materials, if a fixed saturation point is set, around this point an abrupt change of permeability values will be obtained ; this sudden change may cause a little problem in the smoothness of magnetic field distribution ; because the magnetic circuits of microwave tubes are too complicated, in the author ' s view, to describe the working state of a magnet system, the working points of magnets can not do it properly but average energy production of magnets will serve ; as to indicate the quality of a magnet system design for microwave tubes, the efficiency of magnetic energy utilization will be a very good criterion
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。The motion orbits, vibration time histories and imbalance response curves of the rotor system at different magnetic field frequencies and densities were measured and compared with those at steady magnetic field
通過測量不同磁場頻率和強度下轉子系統的運動軌道、振動時間歷程和不平衡響應曲線,並與恆定磁場下的結果進行了比較。The analytic result shows the higher fieldunification is produced between contact gap by the coil type double - pole amf contact structure, and its intension is over 2 times than quadrupolar contact structure when they are in same current
分析結果表明,這種線圈式兩極縱向磁場觸頭結構在觸頭間隙上產生的縱向磁場分佈均勻程度較高,強度要比線圈式四極觸頭結構同等電流下大兩倍。The comparison between the magnetic properties of ndfeb magnet by microwave magnetic field sintering and those of magnet by conventional sintering technology shows that the brwas improved 50 %, the hcb was improved 8 %, and the ms was improved 40 %
