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。 -
Agricultural informatization build - up ( aib ) is one important parts of china ' s information construction. aib is intended to develop and apply modern information thchnology into the field of agriculture in a wide comprehension in order to infiltrate it into agricultural production, exchange, marketing, consumption, distribution and various concrete links in the rural economic development, thus raising the agricultural production efficiency and level drastically. in this article, the author makes an exposition on the basis of the analysis of the information development situation at home and abroad by taking basic theoretical research as the basic point. this article is composed of threesections : firstly, detailed exposition basic intension of the agricultural informatization, staring with the analysis of information conception, attribution and function, and the analysis of reason, function and significance of the agricultural informatization ; secondly, analysis on the current situation of china " s agricltural informatization build - up and brilliant exposition on the possibility, necessity and urgency of aib, starmg with chinese agricltural current situation, international and domestic informatization construction situation, especially the confronted problems in chinese informatization construction ; thirdly, discussion of the development strategy of chinese agricultural informatization in the practice and conception, contert and direction, method and measure to aib in the light of chinese national conditions by using the successful experience
農業信息化就是在農業消領域全面地發展和應用現代信息技術，使之滲透到農業生產、交換、市場、費、分配以及農村經濟發展的各個具體環節，從而極大地提高農業生產效率和農業生產水平。本文試圖以基本理論研究為基點，在分析國內外信息化發展形勢的基礎上進行論述。全文由三個部分構成：第一、從分析信息的概念、屬性、功用及農業信息化的動因、作用、意義入手，比較詳細地闡述了農業信息化的基本內涵；第二、主要從中國農業現狀、國際國內信息化建設形勢，尤其是我國信息化建設所面臨的問題入手，分析了我國農業信息化建設的現狀，論述了農業信息化建設的可能性、必要性、迫切性；第三、針對中國國情，借鑒成功經驗，主要從農業信息化建設的實踐與構思、內容及方向、方法和措施等方面論述了中國農業信息化的發展戰略。
