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。 -
According to " the measuring scale for youth ' s identity crisis " made up and modified by mr. jiang nanfa based on eriksen ' s identity theory and " the survey table for deviation behavior " made up by the author, the study studies quantitatively 406 students from vocational schools, surveying their identity crisis condition and deviation behavior characteristics from the times viewing angle, whose findings after being filtered suggests there are remarkable school type differences and the student gender ' s differences in all kinds of deviation behavior of vocational school students, the deviation behavior of senior vocational school students being relatively less than that of junior vocatio nal school students and the deviation behavior of boy students being remarkably more than that of girl students, and that there are school type differences in a field of identity crisis, identity crisis degree existing in senior vocational school students being the lowest of all among 3 types of vocational school students and all fields of identity crisis being differently interrelated with deviation behavior
本文採用由江南發根據艾里克森的同一性理論編制和修訂的「青少年的同一性危機量表」及自編的偏差行為調查表，對406名職校生進行定量研究，從時代的視角調查他們的同一性危機狀況和偏差行為特點，所得數據經統計檢驗發現：職校生在各類偏差行為上存在顯著的學校類型差異和性別差異，高職生的偏差行為相對較少，男生的偏差行為顯著地多於女生；職校生在同一性危機的層面上存在學校類型差異，高職生同一性的危機水平在三類職校生中最低；同一性危機的各層面與偏差行為表現出不同的相關程度。
