化工知識不僅包含了一般化學知識的內容，還帶有化學生產工藝流程及典型設備的介紹，如接觸法制硫酸，硝酸的工業製法（氨氧化法） ，合成氨工業，電解食鹽水製造氯氣和燒堿，以及電鍍、煉鋁、煉鐵和煉鋼，水泥和玻璃的生產簡介，石油的煉制等，因此，化工知識教學與一般化學知識教學相比，應有其典型的方法。在過去，化工知識的教學一般都採用口頭講解的方法，現在大多數教師也是採用口頭講解的方法，這樣使得化工知識的教學乏味，學生對化工知識的學習缺乏興趣，又因重視雙基，輕實踐，學生對化工知識的學習可以說流於形式。由於多媒體的輔助教學的高效性、形象直觀性、新穎性和多樣性、人工模擬等特點，很適合化工知識的教學，應用多媒體教學化工知識可以解決目前存在的諸多問題，如：模型短缺、組織參觀活動困難、教育經費不足、學生不易觀察等。Displays is functioned under the electromagnetic theory and can be easily effect by the magnetic field. however, please notice that most of the speaker has built - in a big magnet which can effect the functioning and level down the quality of the displays. please do not use your monitor when magnets or electronic products such as speakers operating nearby
電腦顯示器是利用電磁原理來運作的，因此磁場干擾的隔離相當地重要，很多消費者都將喇叭放在顯示器兩側，而市面上防磁喇叭的防磁效果不一，因為喇叭後方有個相當大的磁鐵，如果喇叭過于靠近顯示器的話，就會造成干擾的情形，甚至於產生著磁現象而影響畫面品質。Though ferro - electricity was recognized in the early 1920 ' s, people still do not clearly understand even its basic characteristics and microstructure because descriptions of the behavior of ferro - electric ceramics remain in their infancy. the mechanism of damage, fatigue, crack and fracture of ferro - electrics should be studied more concretely not only in theory but also in application
人們雖然對鐵電現象很早就有了認識，但對其基本性能的認識還遠未完善，對材料的微結構、疲勞、損傷、斷裂、破壞失效的機理也不十分明了，迫切希望進行更深入、更全面的了解。Analysis of ferromagnetic resonance produced in voltage transformer of power distribution system
供電系統中電壓互感器鐵磁諧振現象分析Given that the drawing of plane arrangement maps of electrified railway contact net is one of the important junctures of the whole contact net design, starting from the perspective of system, the paper firstly analyzes the drawing task of the plane arrangement maps of railway contact net in details and presents the structure and function of the system, secondly discusses the formulation of consumer menu and dialogue frame and lists the main controlling program of dialogue frame, then by analyzing the involved data of originally drawing course gives and realizes the management of the original drawing data, which achieves the drawing of choosing inter - station and station, the establishment of drawing papers and drawing form, the setting - up of character height and the drawing form coordinate points and drawing starting points and the preserving routes of data documents of drawing form and the note - marking column and the size of subsidiary table
系統是基於autocad2002平臺，在visuallisp環境下，採用面向對象的編程方法，運用參數化設計的原理，設計開發了運行於windows9x ~ xp上的電氣化鐵路接觸網平面布置圖參數化繪圖系統。電氣化鐵路接觸網平面布置圖的繪制是接觸網整體設計中極其重要的一環，本文從系統的觀點出發，首先對鐵路接觸網平面布置圖的繪制工作做了詳細分析，提出了系統的結構和功能；然後詳細討論用戶菜單及對話框的定製，並列出主要的對話框控製程序；接著通過對初始化繪制圖形過程中所涉及的數據的分析，提出並實現對初始化繪圖數據的管理。The la - modified thin films with 220nm thickness exhibited diffuse phase transition through the testing of temperature dependence of dielectric permittivity. the abnormal dielectric phenomenon was explained according to the observed relaxor behavior. the influence of post - annealing on the properties of the ferroelectric thin - film capacitors is another component of this thesis
在薄膜的介電性質方面，通過對介電溫譜的測試，發現對于厚度薄至220nm的薄膜，摻鑭后同樣會導致馳豫型的鐵電相變，並依此解釋了介電常數的「反常」現象。The same with normal metal film, fe0. 3cu0. 7 ( 500nm ) granular film have positive coefficient of temperature. the negative resistance is observed in fexcu ( 1 - x ) granular film under certain condition. this characteristic of negative resistance is weakened or changed to positive with the change of thickness of film, ratio of fe atom to cu atom, anneal, test temperature
