Various methods such as the relationship of area, and the distance of the triangle to the centralness of three dots, the distance from the interior point, exterior point, the barycenter to the vertices of triangle, and the standard error and differences average obtained from three dots were determined with a dynamic geometry software GSP, and a statistic method was used to find a least error way to determine the centralness of three dots on a plane.

本研究是以平面上三点所构成的三角形之三顶点做讨论，分别以三角形的面积、周长，内心、外心和重心至三顶点距离，三点的标准差及平均差的概念，做为不同的判别方式，并以动态几何画板 GSP模拟不同的判断方法作为研究，再利用统计学上的方法，找出哪一种定义方式为最适合、误差最少的判断方法。

A third order ENO finite volume method for hyperbolic conservation laws on unstructured triangular mesh is introduced.In order to obtain the third order accuracy on spatial discretization,a weighted quadratic interpolation is constructed on every triangular mesh.Two point Gauss quadrature formula is also used on each edge of every triangular mesh and the third order TVD Runge-Kutta method is used for time discretization.The numerical order of convergence and the numerical result of a mesh 3 wind tunnel with one step are given.

摘 要 基于双曲型守恒律方程，对非结构三角形网格给出了一种ENO(Essentially Nonoscillatory Scheme)型有限体积格式，方法的主要思想是先对每一个三角形单元构造一个加权的二次插值多项式，而在计算交界面的流通量时采用了两点高斯积分公式以保证格式的整体精度，时间离散采用三阶TVD Runge-Kutta方法。

The properties of Delaunay triangulation guarantee the following things:Once the fingerprint is given, that is a group of 2-D points are given, the Delaunay triangles are exclusive.
