Partially prestressed concrete structure has been widely used in the field of civil engineering. the deformation is very important for prestressed concrete members, for they are thinner than those of reinforced concret owe to the adoption of hign - intension material and developed technic of design and construction. at present, there are some formulae for deformation in the criterion of many countries. mostly there are 3 methods in use : double linearity method, method of valid inertia and curvature integral calculus method. this article will discuss the influence of material, spa, construction form, and adjust the formula for stiffness of gb50010 - 2002 to a new uniform formula for deformation
在土木工程領域，部分預應力混凝土結構因其良好的跨越能力和經濟性而得到了廣泛的應用，並發揮了巨大的作用。由於採用了高強度材料並進一步改善了設計和施工技術，預應力混凝土構件一般比普通鋼筋混凝土構件更為細巧，因此，撓曲變形問題顯得尤為重要起來。目前，各國規范對于部分預應力混凝土構件的變形計算均有相應的公式，變形計算的關鍵是剛度的計算。 -

With the using of microsoft visual basic 6. 0, a multimedia computer - aided design system of small type pumping irrigation district is developed in this paper. provided with the live multimedia messages as well as a good man - machine conversation mechanism, this system can help the user to finish the planning of an pumping irrigated area such as the layout of canal system, the selection of pump models, the establishment of the irrigation program, the calculating of canals " parameters, the estimate of the project magnitude, the selection of the field constructions, the economic analysis of the project, the output of results, etc, a new oo ( object oriented ) programming method is adopted in this system, various softwares are integrated in this systems as well by the " automation " technic provided by vb, in addition, the multimedia technic is applied to this system for the first time, it makes the system easy to ope rate. as for the optimization of the canals " section, a new optimization method is adopted based on the existing theories about the canals " section, and in this way, with the purpose of minimizing the project ' s investment as well as a stalized canal, limited by the longituding slope, the canals " best feasible parameters can be deduced. furthermore, a integral method to reckon the earth work is developed in this paper, by this way, the estimate precision of the earthwork is enhanced notably. this paper includes the particular illumination for the developing procedure of each systems " segment, and in the end, the directions of the system are demonstrated in a sample area which lies in the zhaija village, taizhou city, jiangsu province, the running results showed that the initial purposes are achieved effectively, and it has a preferable practicability
在渠道縱橫斷面優化方面，本文在利用已經比較成熟的縱橫斷面優化理論的基礎上，提出以工程總費用最小為目標函數，以渠道縱坡i為控制變量，以渠道不沖不淤流速及灌區允許地面比降為約束條件，通過縱橫斷面聯動優化的方法得到渠道的最佳工程可行的斷面參數。另外，針對部分地區的取土困難的狀況，本文採用積分法計算渠道工程土方量，從而大大提高了土方量的估算精度，有助於準確控制工程投資規模及資金投向。本文詳細闡述了該系統所採用的編程方法、系統構成、系統各組成模塊的開發過程以及灌區規劃所採用的優化方法及原理，最後應用本系統對泰州市翟家村機電灌區進行規劃設計，運行結果證明其操作比較簡便，界面友好，運行速度快，規劃成果合理，基本達到了系統預定的要求，具備較強的實用性。 -
The ids works by two way, misuse detection and anomaly detection, misuse detection flags an intrusion on intrusion signature, this kind of detecting technic can be realized much more easily, and much more accurate, but it can not find some intrusiones that have been disguised or new kinds of intrusion. the anomaly detection can detect in more wide field, anomaly detection can compare new statistic data with average record, then anomaly record will be found, but it ' s more difficult to set a threshold, if the threshold is too big, some intrusion may be put through, if the threshold is too small, the ids will give more false positive alarm, and the threshold will be different with different people or different period, so the ids just simply show us their suspicious record, the administrator or expert will be in duty to analyze this record and give conclusion, the ids give more alarm than it should, leave us more detection record to analyze, and this is a hard work, we can not distinguish an intrusion or not if we analyze only one record, but we can judge if we find the relation among mass detection evidence. in this article, we try distinguish an intrusion using d - s theory ( proof theory ) instead using manual work, the ids will be more helpful and efficient
濫用檢測採用的是特徵檢測的方法，實現較為簡單，判斷的準確性較高，但是不能判斷一些經過偽裝的入侵或特徵庫中尚未包含的入侵，異常檢測能夠根據以往記錄的特徵平均值，判斷出異常情況，但是對于異常到什麼程度才視為入侵，這個閥值非常難以確定，閥值設定的太高，有可能漏過真正的入侵，如果設定的閥值太低，又會產生較高的誤警率，而且這個閥值因人而異，因時而異，因此現在的入侵檢測系統把這部分異常記錄以一定的形式顯示出來或通知管理人員，交給管理人員去判斷，而這些ids系統難以判斷的記錄，如果對每個證據單獨地進行觀察，可能是難以判斷是否是入侵，而把許多先後證據關聯起來，專家或管理人員根據經驗能夠判斷訪問的合法性，本文試圖引入人工智慧中證據理論的推理策略和示例學習方法，代替人工檢查分析，可以提高效率，降低誤警率，並可以對一個正在進行得可疑訪問實現實時檢測，通過搜索及時判斷，及時阻斷非法訪問，比事後得人工處理更有意義。 -
