  1. Firstly, this paper introduces the asynchronous motor model, and compares it with the dc motor ’ s. then the paper studies the principle of vector control, and proposes an improved current model of rotor flux observer. this paper also studies the three - level inverter ’ s topology, working principle, the neutral - potential unbalance mechanism and its controlling strategy. the paper especially studies the svpwm in details. the interface between the vector control and the three - level inverter is studied in details, including the generation of reference voltage vector, its judging of the sector and triangular regions, and the working mechanism after it sent into three - level inverter. when synthesizing the reference voltage vector, select the vector which only includes p and o states as the starting vector, thus eliminate the vector shift problem when sector changes. this paper fully takes advantages of the powerful functions of matlab / simulink to set up the simulation model. this construction is very explicit. the simulation results verify the inverter voltage output is correct, the rotor flux is steady, the asynchronous motor ’ s dynamic and steady state performances and speed modulation are excellent

    本文首先介紹了異步電機的數學模型，在此基礎上將異步電機的數學模型與直流電機的數學模型進行了比較;然後介紹了矢量控制的基本原理，採用了一種改進的轉子磁鏈電流型觀測模型;對三電平逆變器的電路拓撲、工作原理、中點電位不平衡的機理及控制方法進行了介紹，詳細分析了空間矢量脈寬調制策略。本文對異步電機的矢量控制與三電平逆變器之間的介面進行了詳細的研究，包括:參考電壓矢量的形成、所落扇區與具體小三角形區域的判斷、送入逆變器之後的工作機理。在參考電壓矢量的合成時，選擇只包含p 、 o狀態的空間電壓矢量作為起始矢量，解決了扇區切換時的矢量突變問題。
  2. When you use the mfc isapi extension dll wizard to create an mfc dll program, you get a working starter application with built - in functionality that, when compiled, will implement the basic features of a dynamic - link library

    當使用「 mfc isapi擴展dll向導」創建mfc dll程序時，您會得到一個具有內置功能的工作起始應用程序，這些功能在編譯后將實現動態鏈接庫（ dll ）的基本功能。
  3. Furthermore, in the original of michael porter, analysis was made on the strategic efficiency based on a given value chain, with no emphasis on the strategic basis of the value chain structure. this was perhaps the main reason of miss - reading, misunderstanding and misusing of the value chain by the business circle or even the academic circle. confronting with this blank in the research area and the present status of the mechanical application, conscientiously or non - conscientiously, of the concept, this paper set forth a goal of clarifying the relation of strategy and value chain and of laying a solid foundation for the value chain structure

    為此本文以嚴守價值鏈的基本概念的態度，遵循企業經營管理展開始於戰略的基本路徑，沿著價值鏈的構造必須建築于深入的戰略分析研究的基礎之上的思路，展開了對價值鏈優化構造的戰略基礎這一命題的研究，並以價值鏈是應對激烈競爭、改變傳統經營模式和恢復或提升競爭能力的現實要求中產生的研究結果作為引導，通過正確的解釋價值鏈的概念、結構和性質，告訴試圖應用價值鏈以解決企業經營實際問題的企業家和管理者們，價值鏈是一個將企業/事業競爭戰略與戰略實施展開的底層作業結合在一起的模式框架，所以缺失了哪一個層面的細致深入的研究而構造的價值鏈都不可能具有內在的有效性。
  4. To tackle this difficult problem, the topic focused crawling technology came into being and occupies a position with its high degree of specialization and objectives in search engine research and development of the next generation search engines. in addition to construct professional search engine, it can be used in a client - based real - time information retrieval system, and has become a new research hot in network information retrieval field
