The goal of this article is : work over the language which is matched the common teaching process based on xml, do research on the logical structure of the courseware, analysis the time, layout element of it and the relationship between these elements. based on these research work, design and implement the authoring system which is based on xml, and then we can quickly generate and usher the xml courseware file
本文的研究目標是：研究符合教學過程的xml形式的課件語言，對課件的邏輯結構形式進行研究，同時分析課件包含元素的時間、空間、以及元素關系等因素，定義符合以上內容的xml文檔結構形式；在以上基礎之上，設計並實現基於xml的課件創作系統，能夠實現基於xml的課件文檔的快速生成和展示。 -
Both are used to separate the responsibility for rendering pages from the model and controller. both accept objects passed into them as an input argument, both allow inserting string values within code " expressions ", and allow direct use of java code to perform loops, declare variable, or perform logical flows " scriptlets ". both are good ways of representing the structure of a generated object web page, java class, or file while supporting customization of the details
Jet與jsp非常類似：二者使用相同的語法，實際上在後臺都被編譯成java程序；二者都用來將呈現頁面與模型和控制器分離開來；二者都可以接受輸入的對象作為參數，都可以在代碼中插入字元串值（表達式） ，可以直接使用java代碼執行循環、聲明變量或執行邏輯流程式控制制（腳本） ；二者都可以很好地表示所生成對象的結構， （ web頁面、 java類或文件） ，而且可以支持用戶的詳細定製。 -
The goal we must achieve, when designing distributed parallel file system, was analyzed also. the thesis present the logic structure of dpfs, the structure and the flush strategy of the module of directory cache and its role in the read - write operation, duplicate table ' s physical and logical structure, the management and synchronization algorithm of the duplicate table, and the model and the management algorithm of the module of intelligent duplicate management. also the effects that dpfs exerts to the system reliability and the read and write performance compared to ext2 were analyzed
本文首先介紹了數據存儲的發展概況與新的需求，分散式文件系統對其發展的重要影響以及設計分散式文件系統需要考慮的各種問題；然後分析了為滿足分散式并行服務器的功能需求， dpfs應實現的目標；接著介紹了dpfs設計的總體邏輯結構，目錄緩存管理模塊的結構設計、刷新策略以及該模塊在文件讀寫重定向中的作用，副本表的邏輯、物理結構、對其緩存的管理和同步演算法的實現，以及副本智能管理的設計模型及其管理演算法的設計與實現，還分析了dpfs對系統可靠性的影響以及在讀寫文件時與ext2文件系統性能的比較。 -
The addressing structure is a b tree populated with extent descriptors the triples above, rooted in the inode and keyed by logical offset within the file
尋址結構是一棵b +樹，該樹由盤區描述符（上面提到的三元組）填充，根在inode中，鍵為文件中的邏輯偏移量。
