    本文對油井水泥供應商在品牌號召力、水泥成本、供應保障能力等方面進行了詳盡分析，並對供應商進行了能力排序;用線性回歸方法從八年鉆井進尺與油井水泥消耗量的歷史數據推算了當年度油井水泥需求量，得出了回歸方程，這對于油井水泥采購合同的制訂、水泥供應商生產計劃的制訂具有相當重要的意義;從運輸彈性分析出發對油井水泥物流配送進行了研究，對直達配送、入庫配送的優缺點進行了詳細的分析，在經濟分析的基礎上力求找到兩種配送方式的均衡點，並提出了經濟半徑的概念，得出了直達配送、入庫配送、入庫分區距離等幾項結論。
  2. If the technicians applied technology in the wrong, even achieving the business logic, but probably leading to many vices including low performance, low scalability, close coupling, low software duplication. so how to assemble the j2ee technology reasonable and achieve a system with high performance and high expansibility is my research emphasis in the thesis. in order to solve the problems and implement efficient web application, the paper put forward ejs _ mvc model according mvc pattern and we can assemble component by using ejs _ mvc model, it can solve many problems of web application and improving system with clear flow and clear function partition, in addition, due to controller is the most importance in the ejs _ mvc model, so the thesis also discuss some problems about controller design ; if the model is not designed accurately, system performance will encounter fatal influence, so the article lucubrate ejb technology from ejb choice, ejb optimized design, database access, design pattern etc and bring forward some strategies and methods about how to build efficient business tier ; finally based on ejs _ mvc model, a example that contains simple business logic is developed according to the object - orient software engineering thinking and some strategies and methods proposed by the thesis, in the process of achieving system function, the emphasis is probing into how t o assemble and apply technology reasonable and providing a new thinking thread and method contributing to build high effective and flexible j2ee application

    由於j2eeweb應用是由組件組成，因此為了解決上述問題，實現高效的應用，本文首先從如何合理組合組件入手，找到一種方法使各組件能具體分工而又緊密合作，在深入研究各組件基礎上，根據mvc模提出了ejs _ mvc模型概念，指出可按此模型組合各層組件，該模型可以解決傳統web開發中存在的問題，而且具有系統流程與系統功能劃分清晰，可擴展性、可維護性強等優點，另外由於控制器是ejsmvc模型的重中之重，它起到承上啟下的作用，它設計好壞直接關繫到整個應用的性能、伸縮性與擴展性，因此又探討了控制器設計的有關問題；另外如果模型設計不當的話，對系統性能造成的影響可能是致命的，因此本文又從ejb組件選擇、 ejb調優設計、數據庫訪問和設計模式等方面對ejb技術作了全面的分析研究，指出在業務層中如何避免太多網路遠程調用和提高業務層性能，特別是根據前面的分析總結出了業務層的優化分層組合模型，這個模型的使用無疑會使業務層具有較高的性能與伸縮性；最後選擇一個業務邏輯較簡單的系統，使注意力集中到運用的j2ee技術上來，按照ejs _ mvc模型與軟體工程流程以及本論文所提出的方法與策略實現業務邏輯，在實現過程中具體探討如何合理運用組合技術，就多層j2ee體系結構的設計思想作深入的探討實踐，為實現高效、靈活的多層j2ee應用提供一種新的思路及方法。
  3. In this paper they study a position - detecting system based on microprocessor and psd ( position sensitive detector ). the method is as follows : when the ac - signal from psd which is illuminated by modulated light source passes through an active band - pass analog filter, it filters the ac signal which represents the object light source. then the dc - converter circuit transforms it into dc - signal which is used to calculate the position

    這一系統採用的方法是通過對位置敏感探測器psd受到調制目標光源照射后輸出的模擬交流信號進行有源帶通濾波，提取出代表目標光源的調制頻率成份，再將該信號轉變為用來參與位置解算的直流信號，然後選用單片機組成硬體電路，對直流信號進行採集處理並與計算機建立通信，把數據送入計算機進行位置解算，分析判別目標光源和psd器件的相對位置。
  4. We utilize the mutual inductor to take a sample to the three - phase current, and sample which is enlarged, rectified, filtered, is send into pic single chip microcomputer to deal with. the size of three - phase current on the line is calculated out, which offer the accurate value for the change of controls the equipment state

    利用互感器對三相電流取樣，然後通過放大、整流、濾波，實現交直流轉換，送入pic單片機處理，計算出溫室輸電線上三相電流大小，為控制設備狀態的改變提供精確數值依據。
  5. Pipelining and parallel technology, accompanying with fast fifo as cache memory, instead of direct program operation, are adopted in the scheme and increase the transmitting speed dramatically ; fpga ( field programmable gate array ) is applied to realize the complex control logic of the system and makes it integrative, flexible and fast ; 386ex based embedded system, along with vxworks real - time operating system is introduced to substitute the microcontroller based system to simplify the hardware design and enhance the overall performance of ssr, and will make the system more easier to be applied to the projects in the future

    該設計方案採用了流水線和并行技術，配以快速fifo緩存的方式取代了直接對flash進行編程的方式，極大地提高了閃存晶元存儲數據的速率；採用fpga技術實現系統的主要控制邏輯，集成度高、靈活性好、速度快；採用基於386ex的嵌入式系統及基於vxworks的嵌入式實時操作系統，取代單片機系統及其編程，提高了系統的整體性能，減輕了硬體設計的負擔，且使系統研發的延續性好。
