  2. This paper describes an aag ( attributed adjacency garaph ) based method of machining features recognition for shaft kind parts and 2. 5d parts on the acis platform, which can effectively recognize the main and assistant feature of these kinds of parts. using the class library provided by acis, all the geometrical information for defining a feature can be acquired. finally a xml neutral file describing the recognition result is provided for the later capp process and the generation of nc code

    本文首先分析三維實體邊界模型的特徵識別方法及其特點，繼而採用基於屬性鄰接圖的特徵識別方法，研究了軸類零件及2 . 5維零件的加工特徵的分類及其識別，並在acis平臺上開發了相應的軟體原型系統，有效地識別該類零件的主特徵和常見的輔助特徵，且利用acis提供的類庫介面提取模型底層的幾何參數，得到定義各項特徵所需的幾何尺寸信息，最後以xml中性文件的形式輸出識別結果，為后續進行的工藝規劃、加工代碼生成提供初始數據，從而為cad / capp / cam的集成提供有效的方法。
  3. 6 we present the query optimization method. for the clustered time series database, the query sequence is classified to one of the cluster, and the efficiency of querying is improved for the similarity search space is limited in the cluster, . 7 we implement a client / server query system and test the presented methods

    根據序列數據庫的聚類結果，將序列數據庫劃分為若干層次的簇結構，通過對查詢序列進行k最鄰近分類，確定查詢序列所屬的簇，然後在相應的簇中執行相似性查詢，實驗結果表』明，基於簇的查詢顯著提高了查詢效率。
  4. In this thesis we firstly made all kinds of statistics on chinese character stroke information of chinese national standard code for information interchange ( gb2312 - 80 ), such as the average strokes of each chinese character and each character which uses utility frequency as its weight, the average strokes of each character been added weight or not that can be differed from the other characters, the number of chinese characters which begin with each stroke, the times of each stroke in the chinese character set, the chinese characters which have same strokes in the chinese character set, and the frequency of adjacent stroke, etc. according to the statistic, we have devised a new chinese character keyboard input method named " stroke code " by adopting the stroke sequence of hand - written chinese character as its input codes and designed a kind of key arrangement for the method

    論文首先統計了國標二級字庫中漢字筆畫信息的各種數據，這些數據主要包括：漢字的平均筆畫數及按使用頻度加權的平均筆畫數、能與其它字區分開的漢字前若干筆畫的平均數與加權平均數、以各種筆畫起筆的漢字數、各種筆畫在漢字字庫中的出現次數、漢字字庫中筆畫相同的漢字以及漢字字庫中相鄰筆畫的頻度等。根據這些統計數據，我們採用書寫漢字時的筆畫順序作為漢字輸入碼，設計了筆畫碼漢字輸入法和實現該輸入方法的鍵盤。
