    水警的歷史源於一八四六年，當時政府首次購置一艘三桅帆船，巡邏范圍只限於海港，兩年後該船隻在臺風中擱淺沉沒，船上十七名水警人員全部喪生。
  2. 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。
  3. Dynamic control of the limit water level belongs to non - structural measures of reservoir operation. with the analysis of the cause and rule of flood in the catchments and taking advantage of hydrology and metrology information, the operable method can be obtained which not only satisfies the flood prevention but also takes full advantage of flood resources, and the upper and lower limits of the limit water level are determined with serial hydrology calculation. then, the rule of using the upper and lower limits is put forward to reach a beneficial flood operation with small risk

    汛限水位動態控制方法屬於水庫風險調度的非工程措施范疇，通過分析流域洪水的成因和庫區降雨及致洪規律，結合水庫的蓄泄能力，積極慎重的利用水文氣象預報信息，研究既能滿足防洪要求，又可充分利用洪水資源的可操作性的調度方法，利用水文系列的連續演算方式推求汛限水位的變化范圍，提出使用汛限水位上下限的原則，達到風險較小、效益較大的目的。
  4. The lower limit of distribution of the masou salmon is the same with that of last year. some individuals can reach as downstream as the in - bin bridge, where the yo - shen creek merges into the chichiawan stream. however, the water temperature at this location usually rises to be higher than 17

    七家灣溪櫻花鉤吻鮭的分佈最下限范圍，與上次的調查結果相同，分佈可以到達七家灣溪與有勝溪會流點的迎賓橋之下，然而此地在夏季由於水溫已經超出17 ，使得櫻花鉤吻鮭夏季的分佈范圍有往上游縮減的趨勢，大致以露營場附近為其分佈下限。
