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

互联网正承载着越来越多的多媒体数据，同一个多媒体数据大多在一个有着共同兴趣的群体里传输，例如在网络电视中观众共同同时收看一个体育比赛，在远程医疗中医生们共同传看一个大型的CT片，传输这些媒体数据需要大量的网络资源，在资源有限、需求开始旺盛的今天，有必要对这些海量信息的传输机制进行研究，以及量少的网络资源(例如路由器、交换机)获得尽快尽好的传输服务。本文的研究动机是解决如何利用现存的网络设施来实现媒体流的高效组通讯的问题。 -The Internet is carrying an increasing number of multimedia data, multimedia data are mostly the same in a group share a common interest in transmission, for example, in the network television audience while watching a sports competition, in telemedicine, doctors look at a common mass large-scale CT films, transmission of these media data requires a large amount of network resources, limited resources, needs to start strong today, there is a need for these massive information transmission mechanism, as well as the less network resources (such as routers, switches ) access to transmission services as soon as possible to do good. This study is motivated to solve how to make use of existing network infrastructure to achieve high-performance streaming media group communications
