閉凸區域 的英文怎麼說
中文拼音 [bìtūqūyù]
閉凸區域
英文
closed convex region-
Under this flow, the convex initial curve will preserve its perimeter, enlarge the enclosed area and make its curvature to be positive definitely. and as the time lasts, it will become more and more circular, and finally, as the time goes to infinity, the curve will converge to a circle in the hausdorff metric
本文證明在這種新的曲線流之下，閉凸曲線周長保持不變、所圍區域的面積不斷增大而曲率保持恆正（從而保持凸性） ，並且，隨著時間的推移曲線變得越來越圓，最終當時間t趨向于無窮大時，曲線在hausdorff度量意義下收斂到一個圓周。Closed convex region
閉凸區域On the basis of the geochemistry digital model arithmetic of triangulated irregular network, i change the arithmetic of auto - tracing isoline. in process of auto - tracing isoline, the proplem of tracing - crossand and mini - heave was resolved. the isoline is smoothec by linear overlap algorithm. in addtion, the model can build other unit of map such as extramum point, polygon
在不規則三角網數字模型的基礎上，改進並實現了等值線生成演算法，解決了等值線生成中的分叉問題，解決了等值線上的小凸起問題；對等值線採用線性迭代演算法進行了圓滑處理；提出延伸三角網演算法，用於實現了開等值線的閉合；生成用於地學分析的區域圖元，等值線圖元，極值點圖元等。
