用三角网法绘制等值线，是在三角形的三条边上用线性内插方法寻找等值点，这种方法的机理是将每个三角形看作是空间的一个平面，这就要求在每个三角形的三个顶点内的地貌形态无明显的变化，故此希望将其中最靠近的三个点构成三角形，以符合上述机理，使插补的等值点精度较高，更好的反映地貌的实际形态。符合这些条件的三角形称之为“最佳三角形”-With a triangular mesh contour map is the edge of the triangle with the three methods of linear interpolation to find the equivalent point, the mechanism of this method is to each triangle as a space plane, which requires each triangles three vertices with no obvious patterns of geomorphic change, it wished to put the three points closest to constitute a triangle in order to comply with the above mechanism, so that the equivalent interpolation points higher accuracy, better reflects the landscape the actual shape. Applying these criteria to the triangle known as the

XML越来越热，关于XML的基础教程网络上也随处可见。可是一大堆的概念和术语往往让人望而生畏，很多朋友问我：XML到底有什么用，我们是否需要学习它？我想就我个人学习过程的心得和经验，写一篇比较全面的介绍文章。首先有两点是需要肯定的： -XML increasingly hot, on the basis of XML Web Directory also can be seen everywhere. However, a lot of concepts and terminology are often people the idea that many of my friends asked me : XML in the end what is the use, Do we need to study it? I would like my own process of learning the views and experience and write a more comprehensive briefing papers. The first two points are needed to be sure :
