  1. 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。
  2. Abstract : it has been discovered that the coke formed in ch4 coupling under plasma can be eliminated via pure h2 discharge in the system. eliminating coke under plasma with positive or negative high voltage in dc electric field has been compared with that in ac field. the elimination of coke takes place only on the negative of the two electrodes in dc field, while on both electrodes in ac field. the coke on the reactor walls can be eliminated with either positive or negative high voltage and in either dc or ac field. based on the experimental facts, hypotheses of the reaction mechanism are suggested. quantity of eliminating coke depends on diametrical ratio between reactor and the electrode, input power and electrode materials

    文摘:發現了等離子條件下甲烷偶聯反應中形成的積炭可以通過該體系中純氫氣放電而消除.將消除積炭使用直流電場的正高壓和負高壓與使用交流電場作了比較，發現直流電場中無論使用正高壓還是負高壓，只有陰極上的積炭可以被消除，而交流電場中兩極積炭均可被消除，反應器壁上的積炭在以上任何情況下均可被消除.基於實驗事實提出了機理假設.消除積炭的量與輸入功率、反應器對電極的直徑比以及電極材料有關
  3. ( 1 ) in newly - constructed stage and early stage of reclamation, the most important factor of runoff is 30min rainfall intensity. in later stage of reclamation, the most important one is 45min rainfall intensity. and the runoff capacity is the most important influence factor to soil erosion always ; ( 2 ) on the certain degree, loosening surface has an active function to infiltration condition but not to conserve soil ; ( 3 ) the most runoff is formed on platform of stackpile and the soil erosion often happens in the slope ; ( 4 ) stone - soiled dumps have an advantage over soil at respect of erosion resistance so that soil is not adapt in covering slope ; ( 5 ) grass has a better role in conservation of water and soil than arbor in early stage of reclamation ; ( 6 ) arbor - arboret - hemp mix is the best model for conservation

    結果顯示：在未復墾時期和復墾初期， 30min降雨強度對徑流影響最大，復墾後期徑流與45min雨強相關性最強，而徑流量對土壤侵蝕量的影響始終最大；通過疏鬆地表巖土只在一定程度上改善地表的入滲條件，並不能起到保土的作用；平臺為徑流的主要形成區，而土壤侵蝕主要集中在斜坡；土石混排坡的土壤抗蝕性比覆土坡的要大得多，在排土場形成過程中不宜用厚層黃土覆坡；在復墾初期，純草模式水土保持效果明顯好於純喬模式。
  4. As the customers require commodities of individuation rather than of popularity, the management should be upgraded accordingly. and the organizational structure of the enterprise changes from the traditional pattern of hierarchies directed by purely cost and efficiency to the flat pattern directed by many target include pursue innovation, then to the pattern of network and so on, as the enterprise supplies products or services aiming at the individual rather than at the mass generally ; meanwhile, it is required that the corporate supply chain should be changed into the relationship of alliance rather than that of purely market trading

    隨著顧客需要從大眾化向個性化轉變時，要求企業管理的質量水平相應的提升，企業提供產品或服務的流程形式從大量生產向單件生產轉變，企業的組織結構隨之從單純成本、效率目標導向的傳統層級型演變到追求創新等多目標的扁平型再發展到網路化組織形式等，同時要求供應鏈從純粹的市場交易轉為相對穩定的聯盟式的關系，並由此引起企業管理形式的變化。
  5. For convenience of grid refinement implementation the nonstaggered grid system based on the structured orthogonal grid scheme is adopted. in order to eliminate the possible pressure wiggles when nonstaggered grid is used, except for the use of the momentum interpolation method ( small wiggles still appear when the method is adopted alone ), a new method is proposed and applied in the same time. in the new method a pressure - gradient difference term is added to the flow velocity in each control volume interface when dealing with the pressure - correction equation

    本文基於結構化正交網格，為便於實施網格加密，採用了變量同位存儲的同位網格體系；為平抑該網格體系下的壓力振蕩問題，除採用動量插值方法外（單純採用該方法不能完全平抑振蕩） ，首次提出了在壓力校正方程的界面流速中添加壓力梯度差值項的方法，從而完全解決了建築風場模擬中同位網格下可能出現的不合理壓力場的問題。
