Following this hypothesis, this study first investigated the topologies of the vowel system across the motor, kinematic, and acoustic spaces by means of a model simulation, and then examined the linkage between vowel production and perception in terms of a transformed auditory feedback experiment
為了獲得切實的證據，我們首先藉助于模型模擬來探索母音體系的拓撲結構在運動指令空間，運動學調音空間，聲學空間的表象，接著通過變形聽覺反饋實驗來檢驗母音生成和感知之間的關聯。( accession numbers : ay184425 - ay184440 ). combined with other several full 12s rrna sequences of chinese water deer, montijac, water deer, cow, horse, goat and tragulus retrieved from genbank database, the whole set of sequences was utilized for downstream analysis based on theories and models in molecular phylogeny, whereas the secondary structure of 12s rrna was predicted and analyzed based on present small subunit of ribosome model
將上述序列與從genbank檢索到的獐、麂、水鹿、牛、馬、羊、鼷鹿的12srrna基因全序列一起，通過應用分子系統學理論與模型分析序列數據，以及對12srrna二級結構的分析，得出了以下主要結論： （ 1 ）用最小進化方法（ me ）和鄰接法（ nj ）對12srrna基因的全序列構建分子系統樹的拓撲結構基本相同。Then in - depth analysed some key technologies including the webpage content extracting, the website topological structure analysis, the website subject analysis & indexing and the website retrieval. especially, some novety solutions, such as the content extraction methology based on the space length of tags, the website tree construction methology based on the similarty of directory in url, and the website concept methology basd on the structure of website, are proposed. finally on the basis of the algorithms and theory, the intellectual websites retrieval system is built and the experiments proved that it can achieve better results
根據以上研究目的，本文首先分析了智能網站檢索技術的構造與實現，提出了基於主題標引的智能網站檢索系統的系統結構與實現策略，之後對系統中的主題分析、標引與檢索等關鍵技術進行了深入分析，針對主要技術難點重點討論了網頁正文抽取，網站拓撲結構分析，網站主題獲取等相關實現技術，提出了基於標簽間距的正文抽取演算法，基於url目錄相似度的網站結構分析演算法和基於網站結構的網站主題概念獲取演算法等解決方案。The key technology related includes website topological structure analysis, webpage content analysis and subject analysis and index. the research is launched for offering service of automatic searching websites. according to the above - mentioned research purposes, this thesis firstly analyzed the system architecture of intellectual website ' s retrieval
基於主題標引的智能網站檢索（ themeindexingbasedwebsiteretrival ， ttwr ）便是以主題網站（ single - themewebsite ）為檢索目標，結合網站拓撲結構等特有的相關特徵，以主題分析標引技術為核心，為提供自動化的網站檢索服務而開展的相關技術研究。In the scheme, ugis classification and coding are divided into three steps : administrative districts are firstly classified and coded, and then street and road with the corresponding code of administrative district added, at last add the code of both the corresponding administrative district and street or road into the code of other corresponding geo - information. this method can reflect topologic relationship between objects, make a fast query and shorten the length of codes
這種綁定式的城市地理信息拓撲編碼的好處是：在編碼中既體現了城市地理信息之間在空間上的拓撲關系，又提高了整個系統查詢和檢索的速度；按行政區劃和城市街道進行城市地理信息的分類與編碼，代碼結構清晰易懂，而且可以大大縮短編碼的長度。The paper carries on the research of network topology, algorithm of state estimation and detection and identification of bad data, and applies the method of tracking search to network topology, semi - dynamic optimization to node numbering, algorithm of weighted least - squares with constraints to state estimation and rn to detection and identification of bad data. the calculation is made for jinzhong ' s electrical network according to its circumstances in shanxi
