The surface panel method has been applied to predict the hydrodynamic performance of highly skewed propeller. the surface of propeller and its trailing vortex are discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution. for highly skewed propeller, the conventional method generating grid oriented along constant radii will result in a high aspect ratio and a high skewness and a twist panel near the propeller tip on blade surface, which result easily in incorrect calculation results of velovity on blade surface, even in iteration divergence and calculation failure. a “ non - conventional grid ” is developed to acoid these problems. this grid can effectively solve the problem of the calculation and convergence for highly skewed propeller. the non - linear kutta condition of equal pressure on upper and lower at the trailing edge is executed by the iterative procedure. by sample calculating, the obtained results are satisfied the experimental data
採用面元法預報大側斜螺旋槳水動力性能，螺旋槳表面及尾渦面離散為四邊形雙曲面元，每個面元上布置等強度源匯和偶極子分佈.對于大側斜螺旋槳而言，槳葉表面採用常規的等半徑網格劃分方法在近葉梢處將導致大展弦比、大側斜和扭曲面元，這容易使槳葉表面速度的計算結果不正確，甚至會導致迭代過程發散及計算失敗.文中建立了一種「非常規網格」劃分方法，能有效地解決大側斜螺旋槳的計算和收斂問題.槳葉隨邊處通過迭代實現非線性等壓庫塔條件 -

In order to solve the problem that current search engines provide query - oriented searches rather than user - oriented ones, and that this improper orientation leads to the search engines ' inability to meet the personalized requirements of users, a novel method based on probabilistic latent semantic analysis ( plsa ) is proposed to convert query - oriented web search to user - oriented web search. first, a user profile represented as a user ' s topics of interest vector is created by analyzing the user ' s click through data based on plsa, then the user ' s queries are mapped into categories based on the user ' s preferences, and finally the result list is re - ranked according to the user ' s interests based on the new proposed method named user - oriented pagerank ( uopr ). experiments on real life datasets show that the user - oriented search system that adopts plsa takes considerable consideration of user preferences and better satisfies a user ' s personalized information needs
針對當前的搜索引擎提供面向查詢、而非面向用戶的服務，從而導致搜索引擎無法滿足用戶個性化的需求這一問題，提出了一種基於plsa的新方法，將面向查詢詞的搜索轉變成面向用戶的搜索.首先，通過分析用戶查詢歷史和瀏覽記錄建立代表用戶模型的用戶興趣向量，在用戶發出查詢時用戶的查詢詞根據用戶興趣向量被映射到興趣分類上，最終根據面向用戶排序演算法將返回結果列表重新排序.實驗表明該面向用戶搜索系統能夠充分考慮用戶的偏好，從而更好地滿足不同用戶的信息需求 -
