  1. The modern technology give a chance for the pattern of transmitting knowledge with network, the course based on network have opened up it ' s way in china, our pursuer paid more attention to the mode, but in america, pursuer have studied the more width aspect, thereinto the investigation and design of the information in the course based on network is very important, for the design of the information decide the pattern how the student receive the information, which will effect the way of knowledge understanding and memory, and the way is related to the study pattern, so the design of the information in the course based on network is very important to the efficiency and effect. so the core of the paper is the investigation and design of the information in the course. i have the entropy from the information science as the analyse tool to analyse the information, these work tell us the efficient pattern to transmit information, based on the result, i design the net page, of course, study theory and the character of the net itself are also the factors i employ for design a good net page. then, links and navigation is constituted for students adapt to the course based on network

    當今技術的發展給知識以網路為媒介來傳播的學習方式帶來前所未有的機遇，網路課程在國內迅速開展起來，但是國內研究者的注意力主要集中在對網路課程模式的探索上，放眼國外，他們的研究觸角已經涉及到網路課程比較細致的方面，尤其是對網路課程信息的研究構成了國外網路課程研究中的比較重要的一個方面，而網路課程中信息的設計是重要的，因為信息的組織設計是為了接受者能對信息進行有效的信息加工，信息的呈現模式影響著學習者對知識的理解和記憶方式，進而決定了學習者的學習模式，因此網路信息的設計在網路課程傳遞的效率和效果中就佔有很重要的位置。基於這個觀念，本文把網路信息的組織設計作為研究的重點，引入了信息科學作為研究的主要工具對網路中的信息作以量化分析研究，主要應用了信息科學中信息熵的公式進行推導，得到學習內容信息組織的基本模式，並充分利用網路自身特性和學習理論對知識信息進行細致的設計，此外還對鏈接和導航信息進行了設計，在網路課程的適應性方面作出了努力，把交互信息與輔助學習信息的分析設計與應用和對網路頁面信息的總體調節優化作為主體信息設計部分的補充，最終形成了網路信息組織設計的方案，力求創設一個能夠有效傳遞知識信息，減少網路自身弊病，並帶有一定適應性的網路學習環境，也使更多的網路課程的設計者關注網路信息這個因素。

  3. 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。
  4. The analysis starts from the introduction of the theory of exchange rates and the relevant economic factors that affect exchange rates. the analysis is based on the following theories : the theory of macro - stabilization policy in open economy, the mundell - fleming model, originated by professor robert a mundell of the department of economics columbia university, who also founded the theory of the optimum currency areas ; another theory is the trilemma by paul krugman. it is concluded that the current stable exchange regime serves as an important guarantee for the fast economic development in china

    面對「人民幣是否應該升值」這個國內外經濟界討論的熱點，本文從匯率決定理論及影響匯率制度的相關經濟因素出發，引用了最優貨幣區域理論的首創者、美國哥倫比亞大學經濟系教授羅伯特? a ?蒙代爾的開放條件下宏觀穩定政策的理論「蒙代爾?弗萊明模型」以及克魯格曼的「三元悖論」等理論來探討人民幣匯率制度的選擇及未來匯率體制的發展目標和前景，明確了目前穩定的人民幣匯率體制是促進我國經濟高速發展的重要保證。

  6. Then, this paper empirically tested the validation and predictive accuracy of different var risk management model in the domestic financial market. finally, with the analysis of modem financial risk management development trend and the current domestic financial risk management situation, this paper made a prospect for the application of this model in the construction of domestic financial risk management system. through the analysis, the main conclusions are as follows : ( l ) the traditional mean - variance model is the special example of the portfolio selection based on the var risk management model for the case that the returns of the portfolio are assumed to be normally distributed ; compared with the mean - variance model, the var risk management model is more comprehensive and accurate in the measurement of the portfolio risk, so based on the var model, the investors can allocate the asset more effectively. ( 2 ) the var risk management model can provide the timely and comprehensive risk information for the top risk manager, so it is very helpful to the improvement of total risk management efficiency. ( 3 ) based on the var model, the raroc performance valuation approach can reflect the real performance of the portfolio manager and provide the coherent standard for the allocation of risk limitation and the construction of the incentive compatibility constraint mechanism in the financial instiutions

    通過研究分析，本文主要得出如下結論： （ 1 ）傳統的markowitz均值? ?方差模型僅僅是在資產組合收益率正態分佈假設條件下基於var風險管理模型進行資產組合選擇的特例，與均值? ?方差模型中的方差風險度量方法相比， var風險管理模型能夠更全面、更貼切地衡量資產組合的風險，且基於此模型能夠更有效地進行資產配置決策； （ 2 ） var風險管理模型能夠滿足更高層次風險管理者對風險信息的需求，有助於整體風險管理效率的提高； （ 3 ）基於var風險管理模型的raroc績效評價能夠反映資產組合管理人的真實業績，從而為金融機構風險限額的分配和激勵約束機制的制定提供統一的標準； （ 4 ）國內證券市場資產組合收益率服從正態分佈的假設明顯不成立，實證檢驗表明基於資產組合收益率正態分佈假設條件下的方差? ?協方差模型對國內資產組合風險的預測存在較大的偏差，由於文中證明在收益率正態分佈假設條件下基於方差? ?協方差模型進行資產組合選擇的結果等價于markowitz的均值? ?方差模型，因此，均值? ?方差模型對國內資產組合風險的預測同樣會存在著較大的偏差，而半參數var風險管理模型則能夠取得較好的預測衡量效果； （ 5 ） var風險管理模型符合未來金融風險管理的發展趨勢，基於var風險管理模型建立內容提要風險限額內控體系、風險信息披露體系和業績評價體系，並進行金融監管，將有助於國內金融機構內部風險管理方法和外部監管技術跟上國際金融風險管理的發展潮流。

  9. Women are supposed to be very calm generally : but women feel just as men feel ; they need exercise for their faculties, and a field for their efforts, as much as their brothers do ; they suffer from too rigid a restraint, too absolute a stagnation, precisely as men would suffer ; and it is narrow - minded in their more privileged fellow - creatures to say that they ought to confine themselves to making puddings and knitting stockings, to playing on the piano and embroidering bags
