  1. Closed curve arc

    閉曲線弧
  2. With fortran power station 4. 0, we make galerkin boundary element method program for solving laplace equation on region which boundary is a closed curve or an open arc, and the numerical experiments also prove this method is reliable. last we test the error of galerkin boundary element by numerical experimentation

    最後利用fortranpowerstation4 . 0程序語言分別編寫了用galerkin方法求解區域邊界為閉曲線及區域邊界為直線段或開弧段laplace方程的計算機程序，通過幾個算例證明了該方法是有效的、是可行。
  3. In the algorithm, the convexity - concavity of vertexes and arcs must be identified, and a fast approach for identifying the convexity - concavity of line - arc closed curve is proposed. firstly, the orientation of a closed - curve is determined by constructing a new convex polygon. secondly, by using the orientation of the closed curve the convexity - concavity of vertices and arcs are identified

    在演算法實現過程中，由於需要對圓弧和直線段組成的封閉曲線的頂點、圓弧的凸凹性進行判定，本文提出了一個圓弧和直線段組成的封閉曲線凸凹性快速判定方法，該方法首先通過構造一中介凸多邊形求出封閉曲線的方向，然後根據封閉曲線方向確定頂點及圓弧的凸凹性，進而確定封閉曲線的凸凹性。
