hydrographic data 解釋
水文資料
  • hydrographic : 水道測量的
  • data : n 1 資料，材料〈此詞系 datum 的復數。但 datum 罕用，一般即以 data 作為集合詞，在口語中往往用單數...
  1. Applying the information extracted from numerous hydrographic data of field trials collected by h / hcs - 017, the first set of multi - beam swath bathymeter developed in china, a series of mosaic techniques have been carefully studied in this thesis, including digital terrain model building, statistical error analyzing, hydrographic data mosaicking as well as tides correction and projection of the earth coordinates. finally, standard digital sea - charts and three dimensional seafloor images are successfully developed that are consistent with hydrographic surveying principles

    本文利用我國第一臺h hcs ? 017型條帶測深儀的測量數據進行拼圖技術的研究，主要研究的內容有：利用分帶原理對深度數據進行潮汐修正，得到瞬時海面的深度數據；對測深數據進行誤差分析處理，去除野值；將多波束數據進行坐標變換及投影轉換后構建數字地理模型，進而根據海道測量規范繪制標準海圖。
  2. With the development of computer technology in hydrographic field, usage of many kinds of advanced and complicate algorithms is not a problem. but because of complexity of geography, acquirement of primitive data needed in hydrographic calculation is still hard to tackle, for example, the length of river segment, the width of every node of every river segment

    隨著計算機技術的發展，在水文學及水資源學科，運用各種先進、復雜的專業演算法求解已經不成問題，但由於地形地貌的復雜性，水文計算中所需的原始資料，如河段的長度，河段各斷面上各個節點處的河寬等數據的人工實地採集工作仍然是很費時費力的事。
  3. But websites that try to offer british tide data have been told by the uk hydrographic office they must pay for it - a cost most are unwilling to endure

    但想要提供英國海潮資料的網站被英國航道測量事務所告知必須付錢，讓人望之卻步。
  4. Besides os, with its vast and valuable map data, there are the uk hydrographic office ( which collects tidal and naval navigational data ), the highways agency ( which collects traffic data ) and even the european centre for medium range weather forecasting

    除了坐擁大量地圖珍貴資料的全國地形測量局，還有收集潮汐和船隻航行資料的英國航道測量事務所，收及交通資料的高速公路局，甚至歐洲中期氣象預測中心。
  5. With the meteorological and hydrographic data in songhuajiang and nenjiang valley from 1951 to 1995, using correlation analysis and empirical orthogonal analysis, the rule of the flood and relation between flood and precipitation distribution in this region are discussed. the results show that periodic change of water level is obvious in this region. now water level is in the serious stage from 1980 ' s. there are great relation between the water level of flood period and the precipitation. the unusual precipitation of nenjiang valley has greater impact than that of second songhuajiang valley. at the summer in 1998, songhuajiang and nenjiang valley encountered the ghastly flood and the reason for that is the anomalous precipitation great exceeding the historic maximum

    利用松花江，嫩江流域1951 1995年期間的氣象和水文資料，採用相關分析，經驗正交分析等方法，討論了該流域洪澇發生的規律及其與流域內降水分佈的關系.文章指出，江流域的水位變化有明顯的階段性，且具有全流域一致的特性，目前正處在80年代以來洪澇較嚴重的階段;嫩江流域降水異常偏多對松花江洪澇的影響比第二松花江的作用要大; 1998年夏季，松花江，嫩江流域出現超歷史紀錄特大洪水的關鍵原因是嫩江流域6 8月的降水距平百分率遠遠超過了歷史上的的最大值
  6. Because the channel bed was adjusted by scouring and silting in long - term, the required period to reach basically equilibrium was predicted based on the typical and assemble hydrographic data in long series after the building of lijia flume dam

    應用李家峽建壩后典型水文年長系列的組合資料，預報了河床經長期沖淤調整后達到基本平衡需要的時間。
  7. On base of the theory studied, the author developed a package of applied mosaicking software, using microsoft visual c + + 6. 0 and opengl graphic techniques. the software was tested with field trial data of h / hcs - 017. digital sea charts generated by the software are satisfactory and meet the hydrographic surveying principles

    在理論研究的基礎上，本文利用visualc + + 6 . 0語言和opengl圖形編程技術，開發出一套適用於多波束測深數據的拼圖軟體，可用於h hcs - 017型條帶測深儀數字海圖的生成。
