  6. Engineering drawing has always been labeled as a practical subject. a combination of geometrical, building. mechanical and electrical drawing, it relates between theory and the picture of reality. engineering drawing will provide an accurate and complete ptcture for every object tn terms of shapes and sizes. usually, it is taught using the face - to - face teaching mode even in an odl environment. due to its nature, some students may find difficulty in imagining and interpreting the drawings. however, the availability of sophisticated technology provides the opportunity for the learning of engineering drawing to be enhanced via online. a web - based system for teaching and learning engineering drawing was developed based on a constructivism model. the web - based system is tailored for several topics of engineering drawing such as orthographic projection, sectional view, isometric and oblique drawing at the secondary level. the learning strategy consists of multiple phases beginning with introduction, concept learning, engineering drawing method, application and exercises. during introduction, students will be exposed to an overview of the topic followed by learning of specific concepts. the system provides a learning environment that allows engineering students to view objects from different angles, such as third angle projection and first angle projection as well as views of plans, side and front elevations. after learning about the concepts, students wilt be guided through the various steps in drawing methods for each topic via animations and simulations. learners are able to view any section repeatedly. examples of real application of engineering drawings were also given using graphic, animations and video. to evaluate students understanding, exercises were given at the end of each session

    工程制圖一直被認為是一門實踐性學科,其整合了幾何學、建築、力學、電子制圖等,從而將理論與現實圖像聯系起來,工程制圖能為每個不同形狀、尺寸的物體提供精確的、完整的圖像.通常,即使在開放與遠程教育環境中,工程制圖的教學也是通過面對面的教學模式來進的.由於其特殊性,一些學習者可能難以想象並解釋這些圖像.然而,尖端的技術使得可以通過在的方式加強工程制圖的學習.研究者基於建構主義模式開發了一個面向工程制圖教學和學習的網路系統.該系統適用於幾種工程制圖,例如展開圖、刻面圖、等角圖和斜角圖.學習過程包括導論、概念學習、工程制圖方法,以及應用與練習等階段.在導論階段,系統為學習者提供了專題簡介,然後是概念學習階段.系統所提供的學習環境允許工程專業的學生從三維透視、一維透視、面圖、側立面、正立面等不同角度來觀察物體.經過概念學習階段后,系統將引導學生通過動畫和模擬學習每個專題中制圖方法的不同步驟,學習者也能觀察任何剖面.另外,還通過圖像、動畫和視頻等方式展示真實的工程制圖應用案例.最後,為了評價學生的理解能力,在每部分內容後面都附有相關的練習

  8. Electrical machines are the most important and main drive devices in manufactures and our daily life. no other kinds of machines can replace them. they are widely used in the modem world. without electrical machines, the world would not be what it is today. when operating, they might have a lot of faults. if a main electrical machine is wrong in a work line, the whole line will stop, even the whole productive system. the phenomenon of the faults are so complicated and various that the maintance worker should be skillful and very experienced. the history of fault diagnosis and protection is as archaic as the machines themselves

    電機是當今生產活動和日常生活中最主要的原動力和驅動裝置,它廣泛地應用於現代工業生產中,它們數量之多,地位之要,幾乎沒有其他設備所能與之相比。電機在運過程中,難免會出現這樣那樣的故障,假如一條生產上的主要電機故障,必將造成生產停工,甚至會影響整個大生產系統的工藝流程。電機的故障現象比較雜,要求維修人員具有較高技術水與經驗,才能發現和判斷。
