  1. In this paper, the main research works are as follows : 1 ) survey and analysis previous work in auv navigation and summarize : as the cumulate error, the dead - reckoning and inertial navigation systems ca n ' t be used without other modified system ; the acoustic navigation system is used only in small range, and is very expensive. 2 ) two important approaches in geophysical navigation techniques are summarized, one is terrain contour based navigation, this approach is investigated keystone today ; the other is image based navigation, due to no perfect image sensors and image seabed map, this approach has seldom been practised. 3 ) two important terrain contour based navigation algorithms has been applied to auv, one is match algorithm - based terrain contour match ( tercom ) ; the other is kalman filter - based sandia inertia terrain - aided navigation ( sitan )

    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。
  2. The transient mathematical equations are addressed for the coupled heat and moisture transfer by taking account of moisture accumulation procedure. an analytical method by means of the transfer function is proposed to predict the transient distributions of temperature and moisture content at different interfaces in walls. a numerical analysis approach based on an efficient finite - difference method is developed to deal with the procedure of coupled heat and moisture transfer in a multilayer wall with nonlinear boundary conditions considered

    建立了考慮濕積累過程的瞬態熱濕耦合模型，在方程中引入了濕積累項；發展了一種傳遞函數解析方法進行墻體內不同剖面處溫度和含濕量的動態預測；首次提出了一種基於有效有限差分法預測非線性邊界條件下多層多孔結構內的傳熱傳濕過程的數值分析方法，求解過程中考慮了瞬態邊界條件，從而避免了通常處理中由於邊界條件設定為常數而給計算帶來的誤差，對于多層結構每一層物性參數的非連續性，則採用了有效的有限差分逼近處理。
  3.

  4. The inelastic demand spectra are established according to the new chinese seismic design code for buildings by means of force reduction factor r and ductility factor u, thus, a simple and practical method is established for seismic damage assessment in combination with capacity spectrum method ; the structure ' s push - over curve of second earthquake is gained by cutting the curve of quasi - test reversal load pattern method, thus, the structure ' s cumulate damage level can be computed by the capacity spectrum method too ; the results of an example are compared with the facts, and the validity and simplicity of this method is approved
