主要研究內容包括：一、總結分析了當前水下導航的常用方法和不足之處，指出基於航位推算的導航方法，存在著最大的問題就是導航誤差的積累問題，如果沒有修正系統，這種方法很難滿足使用要求；其次指出基於聲學的導航方法，造價昂貴，導航范圍有限，難以滿足自主水下航行器大范圍導航的需求；二、總結了當前水下地形輔助導航的主要技術路線，一是基於地形高程的匹配方法，這是當前研究的重點；二是基於地形圖像的匹配方法，由於缺乏良好的圖像傳感器，和可用的海底圖像地圖，目前這種方法還有待研究發展；三、將兩種地形高程匹配的常用方法應用到自主水下航行器上：以相關演算法為前提的地形輪廓匹配（ tercom ）方法和以卡爾曼濾波為基礎的桑迪亞慣性地形輔助導航（ sitan ）方法，前者演算法簡單可靠，但是導航精度不高，後者雖然精度比較高，但存在著演算法較為復雜、有可能發散和出現奇異值等問題。The result shows this measure system is very simple, performance reliable, operating convenience, and its precision approaches to 1 %. it takes an important role in large - scale measurement and in practice the new method shows stronger practicality and popularly application prospect
實驗結果表明：該測量系統非常容易獲得大視場的正弦光場，且系統裝置簡單、不需要相移器、操作方便、穩定和重復性好，其測量精度達約為1 ，在大尺寸物體的三維輪廓測量中具有實用性和推廣應用前景。Based on the mechanism of computer immune system, this paper presents a new anomaly detection technique to detect intrusion into computer system. in this technique, a markov chain model is used to represent a temporal profile of normal behavior of a process. the markov chain model of normal profile can be created by learning the historic data of the sequence of system calls produced by privileged processes running on unix system
傳統的入侵檢測技術，依照所基於的原則不同，通常分為誤用入侵檢測與異常入侵檢測，本文在入侵研究中所採用的計算機系統免疫思想的基礎上，提出了一種新的異常入侵檢測技術，通過對（ unix系統）特權進程系統調用序列的歷史數據的學習，用馬爾可夫鏈模型來建立特權進程的正常時態行為輪廓。The nose is 1 of the most important characters in the human facial profile, and it is also a good reference for the evaluation of orthodontic treatment
摘要人類鼻部是側臉輪廓上的重要特徵，齒顎矯正治療也常需考量鼻部側面形態。For the graph entities with arc type, we mainly studied a mis - recognition in graph entity types, referred as " pseudo arc ". by searching the corner points on the border of the arc and divide the arc to piece - wise, the analysis is then done for every piece respectively
對于圓弧型圖素，則重點研究了常見的錯誤模式?偽圓弧的檢測和校正技術，首先檢測偽圓弧對應的光柵圖元輪廓上的角點，並以這些角點對圖元輪廓進行分段，再逐段分析。These two - layer markov chains were used to construct the normal profiles of server process ' s activity, and then to detect anomaly
