  1. The proportion that the sediment yield of the main gully accounts for the total sediment yield of the experimental watershed model is from48. 7 % to 66. 6 %, and the proportion that deposition sediment yield of main gully accounts for the total deposition sediment yield of the experimental watershed model is from64. 9 % to 99. 4 %. the developing process of topographic feature of the experimental watershed model. expanding the gully width and cutting down the gully bottom are the two chief forms of the topographic feature development

    流域模型地貌形態發育過程溝谷擴展和下切是流域模型地貌形態發育的主要形式，溝谷擴展發育主要發生在發育活躍時段，主溝所佔溝谷總面積比例在流域模型溝谷擴展發育過程中保持在60以上：主支溝下切發育在發育初期和發育活躍時段前期表現最為劇烈，其橫剖面為v字形，在發育初期和穩定時期時段呈現淺u字形和底部較為平坦的梯形，主溝的橫剖面發育明顯優先於各支溝。
  2. The topographic feature is one of the main factors that influence the process of soil erosion and sediment yield of small watershed. the quantitative parameters of small watershed topographic feature are average watershed slope, average slope length, gully density and so on, which are based on the quantitative method of slope character and do not reflect the essential character of the small watershed topographic feature, which are complex

    地貌形態是影響小流域侵蝕產沙的主要下墊面因素之一，其量化參數一般繼承坡面地貌特徵量化方法（如坡度、坡長因子）而採用平均坡度、平均坡長及溝壑密度等參數，這些參數僅是對流域地貌形態的概化和單因子表達，沒有真正反映流域地貌形態復雜的本質特徵和相互聯系。
  3. Based on the fractal character of the small watershed topographic feature, the spatial and temporal variation character of sediment yield of the watershed model, the dynamic developing process and fractal character of the topog raphic feature of the watershed model, and the coupling relationship between the sediment yield and the topographic feature of the watershed model are " studied by simulate experiment, fractal theory, high precise photogrammetry and gis technology. the validation research is conducted in chabagou watershed where the observation data of rainfall, sediment and runoff for 11 years is collected. the study provides new theory and method for the topographic feature quantitative research in the prediction model of small watershed sediment yield

    本文依據流域地貌形態所具有的顯著分形特徵，從模擬實驗出發，利用分形理論和方法，結合高精度攝影測量和gis技術，對流域模型侵蝕產沙時空變異特徵、地貌形態發育過程及其相應的分形特徵、流域模型侵蝕產沙與地貌形態耦合關系進行了深入研究，並以具有11年降雨泥沙徑流觀測資料的岔巴溝流域為例進行了驗證研究，為實現從單坡面侵蝕產沙模擬、預報向流域侵蝕產沙模擬、預報轉化過程中地貌形態參數的提取提供了理論和方法，為黃土高原小流域水土流失綜合治理提供了科學實踐依據。
  4. Another major feature of this product is that it can be flexibly installed response to the topographic conditions of specific sites such as slopes and undulations, etc. with a variety of wire rod and processed mesh, knuckle types available, the potential uses of our mesh are almost unlimited

    菱形金屬網是利用加工成螺旋狀的金屬絲組合連接而成的，容易拼接和切割，另外，其特點是通過豐富的線材，加工網眼，關節種類，在斜面，凹凸面等各種狀況下均能使用自如，具有無限使用可能性。
  5. Dc91 - 200 artillery topographic vehicle has equipped in car artillery topographic elemeat recently. it is a new equipment which can determine fix and direction making use of intertia measurement fix and direction making use of intertia measurement principle. the rehicle has many feature advantages : maneuver, rapidness, exactness and automatic fix. in order to put it into operation, the paper analyzes its working features and discusses its operate method in combat. on the basis of that author then gives us a more deeply and systematically research about the reasons of topographic discrepancy and elements which influence its operation efficiency. a series of comparation experiments are offered at the same time

    Dc91 - 200型炮兵測地車是新近裝備於我軍炮兵測地分隊的利用慣性測量系統實施定位定向的測地新裝備。為充分發揮dc91 - 200型炮兵測地車快速、機動、準確定位定向的性能優勢，使其盡快形成戰鬥力，本文從分析該車的工作特性入手，探討了其在作戰中的使用方法，在此基礎上，就產生測地車測量誤差原因、影響作戰效率發揮的因素及提高措施等問題進行了深入地研究。
