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。It is inevitable that some crane ' s parameter such as working temperature, actual span and so on will change because of the affection of install precision, the change of working condition and actual needs. as a result, it will affect the tension force of carrying cable and carrying capacity. and the tension force and carrying capacity have close relation to the performance of cable crane and operational security
由於纜索起重機工作環境和性質的特殊性,安裝精度的影響、工作環境的變化以及實際工作的需要,不可避免的會引起的各項參數的變化,如工作溫度,實際的跨度等,造成與設計參數之間的差異,從而影響承載索的張力和承載能力,因而直接關繫到起重機的性能和生產的安全性,因此論文研究這些因素變化對張力和承載能力產生的影響,分析張力及承載能力對各因素變化的靈敏度,從而對生產實踐和安全生產作出有意義的指導。This paper is intended to briefly account the explorations of curricular construction, student autonomy and the like reforms performed by shu xincheng in shanghai public schools in line with the daltonian system, so as to demonstrate shu ' s charming personality in his courage to introduce and adapt the reformsto the chinese education

論文根據現有標本對中國廣頭葉蟬亞科進行了系統的分類研究,全文共記述了廣頭葉蟬11個屬共45種,包括4新屬、 26新種、 2中國新記錄屬、 9中國新記錄種、 2新組合;編制了分屬、種檢索表,繪制了全部新種的外部主要形態特徵圖和雄性外生殖器圖,文末附有主要參考文獻和索引。新分類單元、新組合、新紀錄如下:新屬:彎背葉蟬屬doroflexusgen . nov . 、指突葉蟬屬digitalsgen . nov . 、細突葉蟬屬tennuisimusgen . nov . 、闊唇葉蟬屬expansusgen . nov . 。As the atom wiki states, the project creates " specifications for syndicating, archiving and editing episodic web sites. " i think that the defining characteristic of the domain atom addresses is not just web sites that are naturally broken into episodes, but also web sites that have a conversational nature through their interchange with other sites ; the episodes are often fueled by cross - reference to similar entries on other sites, and atom intends to be the glue for this interchange
如atom wiki所宣稱的那樣,該項目要建立「連鎖、存檔和編輯情節式站點的規范」 。我認為, atom處理領域的定義特徵不僅僅是自然分解成情節的web站點,還包括那些與其他站點交互中具有會話性質的web站點。情節往往帶有對其他站點上類似實體的交叉索引, atom就是為了把這類交換粘結在一起。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。All the clippings are non - circulating materials and users can use them for educational and research purposes at the special collections & archives, level 4 of the main library
