  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. In this paper, the authors probe into the characteristics of regional gravity field, residual gravity field, structure of the earth ' s crust and regional tectonics on the basis of the bouguer anomaly map in combination with other geological and geophysical data

    摘要本文利用布格重力異常圖，結合其它地質和地球物理資料，探討了青藏高原區域重力場和剩餘重力場特徵及所反映的地殼構造。
  3. The non - linear inversion methods are developed to overcome the difficulties met when the linear inversion methods are used in the geophysical inversion problems. this paper presents the simulated annealing is hopeful for the inversion problem of resistivity map reconstruction. due to the slow speed caused by the global searching, so for, the method is limited in the processing the 1 - d model

    為了克服像傳統線性反演方法中解易陷入局部極小的不足，本文採用了模擬退火這種非線性方法實現了高密度電法一維反演，初步取得到較好反演結果，但由於它隨機搜索全局解空間，計算量非常大，因此目前主要應用於一維地電結構的反演。
  4. Mine forecast map of integrating information is accomplished by analyzing geological disciplinarian according to geological map and integrating explaining for geophysical and geochemical and sand and remote sense data and relating every integrating information to geological body and picking up information related with researched body

    綜合信息礦產預測圖是以地質圖為基礎，通過地質規律的分析，在地質先驗前提下，對物探、化探、重砂和遙感等資料進行綜合解釋，以地質體為目標，對各種綜合信息進行關聯，提取與研究對象有關的信息編制而成。
