Gathering fuzzy technique and model - identifying technique to processing research, fuzzy model - identifying technique, a intersecting science, has been come out, which has become hoto in this thesis, based on deeply researching the fuzzy unit - identifying and complete analysis on data of measuring well of the chandqing wushenqi district, the method of constructing self - adapting multi - dimension non - liner subjection degree function has been created without precedento based on the extraction of routine measuring well character parameters, and for adopting self - adapting method to carry through character compression, the model has been improved the performance and enhanced the convergence speed and sorted precision of the algorithm o the relation of measuring well information and the oiliness & gassiness of sandstones is fuzzy ? in the thesis, the law of max subjection degree has been studied and improved, and proved preferable effect in the practical application
論文在提取一些常規測井特徵參數的基礎上，採用自適應方法對各變量多項式進行優選，減少了特徵參數間的相關性，突出了類別間的差異性，從而優化了模式的質量，提高了分類的精度。測井信息和砂體的儲集性之間的關系是帶有模糊性的，論文對模糊「最大隸屬原則」進行了研究和改進，並在實際應用中取得了較好的效果。論文成功研製了「自適應」的演算法和軟體? ?即通過對正確回判率的比較，然後對參數進行調節的辦法，可將模式「訓練」到最佳狀態。Our results provided direct evidence that pf40 gene play a role in the tissue development, with knockout this gene the lateral buds were not visible. the plant hormones auxin and cytokinin appear to play a major role in controlling this process, therefore, the concertrition of auxin and cytokinin was measured, however, the concentration of the two hormone was variation a little in transgenic plants, but the ratio of the two was more than 5 fold in the pf40 gained function plant than that in wild type. furthermore the pf40 gene effected differentiation of the vascular bundles in different transgenic plants, results showed the pf40 could change both xylary fibers and vessel
進一步的實驗發現pf40基因會影響植物側芽發育的早期，即pf40基因作用在側芽形成與發育的早期。對轉基因穀子的組織切片的分析還表明pf40基因引起不同形式的轉基因穀子的維管組織的發育的差異，轉化正義載體穀子的木質部變多，維管系統增多，而反義或干擾的轉基因穀子的木質部數量變少，木質部分化異常。從轉基因的結果可見pf40基因可以減弱植物的頂端優勢，這種作用是通過改變植物體內激素的含量實現的。According to the principles of unequilibrium electric bridge, this paper analyses the work features of the three bridge types and based on experiments, shows how to select the bridge types and parametes. to reduce the non - linear errors and avoid centain unusual circumstances in the measurement
從非平衡電橋測電阻原理出發，分析了3種橋式的工作特性，並通過實例說明如何選取電橋的橋式與參數，以減少測量的非線性誤差及避免一些異常情況。It solves payment issue through sharing pos and brush card. it solves info sharing and exchanging problem by enterprise application integration it adopts research method of software engineering and uses touch - screen, network, database technology and so on to carry through total design of the system and build the software : it uses user status identify and responsibility control to ensure database and application program ' s security ; it strengthen the code by coding optimize ; it captures and discards application runtime error to enhance the system ' s stability ; it uses multimedia voice and moving picture to show help information, thus makes the system easy to use ; it greatly reduces the maintenance work of the system by self - updating function ; it is an opening system by using star - model network top structure, supporting standard network communication protocol ? tcp / ip and offering standard software interfaced criterion
論文採用軟體工程的研究方法，使用觸摸屏、網路、數據庫等技術，進行了系統總體方案設計和軟體開發：通過對數據庫和應用程序的用戶身份識別和權限控制，保證數據存取和應用程序的安全性；通過對代碼進行優化提高了代碼的健壯性；通過捕捉並拋出系統運行時的異常錯誤提高了系統的穩定性；通過多媒體語音、圖形和動畫提示幫助信息來增強系統的易用性；客戶端程序自動升級功能提高了系統的可維護性，有效地減少了維護工作量；系統採用星型的網路拓撲結構，支持標準的tcp ip網路通訊協議和規范的軟體介面標準，具有良好的開放性。Following the two crows data mining process model, the product data, transaction data and customer ' s demographic data are accumulated, such data is preprocessed by the primary component analysis method which can low the connection of variants and reduce the number of variants. one model is built by the improved dynamic cluster method. the quality of the model ' s result will be improved with deleted the outlier data
參照twocrows數據挖掘過程模型，首先收集客戶購買產品的類型、交易、屬性等數據；然後採用主成分分析法預處理這些數據，以降低數據之間的相關性和減少變量個數；接著採用改進的動態聚類方法建模，在聚類過程中剔除異常點，改善聚類的質量，最終得到一個客戶分片的模型，並對該模型作了比較詳盡的解釋。Once the view is created by outjoin, those existing algorithms may fail in view maintenance. this paper introduce a new view maintenance algorithm, which can handle view involving outjoin, regular join and data inconsistency. moreover, our maintenance mechanism minimizes the number of the queries that need to be sent to the local database systems for view maintenance, which is an efficient way to make the multidatabase system more efficient
針對傳統的視圖維護演算法在有外連接或數據不一致的情況下會出現錯誤的問題，本文提出了一種新的視圖維護演算法： vmdt演算法，該演算法不僅解決了外連接及數據不一致問題，而且最大限度地減少了國防科學技術大學研究生院學位論文mdbs與ldb之間的通信量，解決了嵌套異常問題。分享友人
