本論文介紹了國內外減震技術的發展和現狀；綜合分析了普通板式橡膠支座和鉛銷橡膠支座的工作機理、性能及參數的計算；提出了鉛銷橡膠支座標準化的概念；在綜合分析場地土、鉛銷直徑、支座高度、設計承載力、橋梁跨徑、固有周期以及支座變位等影響因素的基礎上，確定了鉛銷橡膠支座標準化的參數、減震目標、方法和過程；並根據抗震設防兩階段原則，結合橋梁地震振動理論的反應譜法，運用有限元程序對收集和組合的實橋進行了大量減震設計的計算和分析；最後以圖表的形式給出了鉛銷橡膠支座標準化的結果，並說明了其使用方法。The common map is scanned into grid map, and then vectored in mapinfo. after vectoring, vector data are matched and the spatial coordinate data of resident points, water system and other data are gained. the coordinate of reference points in the freeway are gathered by gps, then after data processing, coordinate transition, data inputting, it turn into the freeway graph, which composes the freeway electronic map with the materials subsidiary to the freeway
將普通紙質地圖經過掃描生成柵格地圖，然後在mapinfo環境下進行矢量化生成矢量化地圖，經過矢量化數據配準，確定居民點、水系等物系的空間坐標數據；利用gps採集的高速公路控制點坐標，經過數據處理、坐標轉換、錄入，最後生成高速公路圖層，和上述高速公路附屬物共同構成了完整的高速公路電子地圖。The design of network video collecting system proposed in this thesis is based on embedded hardware developing platform with motorola mcf5272 chipset as center chipset, and uclinux as embedded system as software developing platform. after collecting video data through a usb camera, the system compresses the data in jpeg picture format and mpeg - 4 video format. then with the embedded web server and streaming server, it establishes connection with client in c / s mode, which enables the client to view the video through browser or normal media player remotely
本設計所提出的網路視頻採集系統的設計是在以motorola的mcf5272晶元為主晶元的嵌入式硬體開發平臺配以uclinux作為嵌入操作系統的軟體開發環境下，通過一個usb介面的攝像頭輸入原始的視頻數據，在嵌入式板上分別採用了jpeg圖像格式壓縮和mpeg - 4視頻格式壓縮對原始的視頻數據進行處理，最後通過內置的web服務器和流式媒體服務器，採用c / s的方式與客戶端建立連接，使客戶端在只要能上網的地方就能通過瀏覽器或是普通的mediaplayer播放器觀看到服務器端採集到的影像，具有十分廣泛的應用前景。In general, a firm begins collecting all kind of materials about economy development and environment after accepting a assignment, and then studying a feasible path based on one of these materials individually. these suitable paths will be compared and outline a final solution
一般情況下，公路設計單位在接受設計委託后，要開始收集項目影響區經濟、交通發展資料和地質水文普查資料、各種比例的地形圖等資料，然後在此基礎上，對單個條件進行研究，再就可能的方案總體對比，才編制出該工程的線路規劃方案。By cooperating with a company and tsinghua university, we can use advanced instrument to measure our own made micro - scale flow models. we got right data results and protract them in frank flow field figure graph. according to the results, we give the reasonable explanation in fluid mechanics
在完全沒有借鑒和經驗的情況下，採用圖像採集卡、常規攝像頭及普通顯微鏡改裝了一臺micropiv ，能夠進行低速微流場的觀測和測量，取得了進行microptv試驗的經驗，同時自行設計製作了微流道，在北京立方天地公司和清華大學的幫助下，使用高速攝像機進行了流場拍攝，取得了可信的試驗結果，並給予流體力學的解釋。Furthermore, the existing algorithms for dynamic query are generally dependent on the static mapping algorithms. to resolve these two problems, a gvrs ( general virtual relational schema ) model for xml document is put forward as a bridge between xml instance document and factual rdb, and an algorithm which transformes xquery into sql and is independent on the static schema mapping, is realized. based on the above approaches, the dynamic data query on bottom rdb is carried out through xml view and the data integration between rdb and xml is achieved on the dynamic query tier
通過xml視圖動態檢索底層rdb的技術建立基於rdb的xml動態檢索機制；針對現有動態檢索演算法大多依賴靜態模式映射演算法的問題以及基於w3c工作草案xquery的研究尚無實質性進展的現狀，通過提出並建立gvrs （ generalvirtualrelationalschemaforxmldocument ）模型，作為xml事例文件與rdb之間的橋梁，實現了一種與靜態模式映射「無關」的xquery到sql的轉換演算法，保證動態檢索對各種靜態轉換的普遍適應性，實現了通過xml視圖對底層rdb的動態數據檢索，較好地解決了xml與rdb在動態檢索層面的數據集成問題，可有效滿足根據用戶需要有選擇動態檢索系統底層rdb數據的需求。分享友人
