Degree sum conditions of IM-extendable graphs are researched. The main results are as follows 1 Let G be a graph with 2n vertices. If for each pair of nonadjacent vertices u and v in G,, then G is IM-extendable. 2 Let G be a claw-free graph with 2n vertices. If for each pair of nonadjacent vertices u and v in G,du+dv≥2n+3, then G is IM-extendable.

研究导出匹配可扩图的度和条件，主要结果如下 1若图G有2n个顶点，且对于G中每一对不相邻的顶点u和v，，则G是导出匹配可扩的 2若G是一个有2n个顶点的无爪图，且对于G中每一对不相邻的顶点u和v，du+dv≥2n+3，则G是导出匹配可扩的。

Have Flex Vml Svg Ajax Applet Activex commonly usedly at present I divide these technologies into two kinds of Flex Vml Svg Ajax for the moment is to use script technology, pure do develop to attack for the graph, do not have a problem absolutely, and those who do is more beautiful, but most circumstance falls, the develop that we need attacks the graph needs to have menu, other interface, user alternant, data processing, this kind is based on script technology, handling this side is too convenient really, be being developed especially and debug on, what come as programming language is convenient. Java Applet and Activex are to attribute programming language skill, without doubt, have powerful interface and process designing capacity, and can ensure whole group is same technology language, can develop in compositive development environment, debug.

目前常用的有flex vml svg ajax applet activex我姑且把这些技术分成两类flex vml svg ajax都是采用脚本技术，单纯做拓扑图来说，绝对没有问题，而且做的更漂亮，可是多数情况下，我们需要的拓扑图需要有菜单、其他界面、用户交互、数据处理，这种基于脚本技术的，在处理这方面实在是太方便了，特别是在开发和调试上，不如编程语言来的方便。java applet 和activex是属于编程语言技术，毫无疑问，具备强大的界面和编程能力，而且可以确保整个团队都是同一技术语言，可以在集成开发环境中开发、调试。

The DTM for automatic-design of thruway was put forward by Prof. Miller in 1956. Since then , the DEM is used for design of various circuit diagram, and for account of area, cubage, gradient of various project, and for estimating visibility from point to point; for rendering contour, grade-graph, aspect-graph, solid model; for making orthographic image and repair map in the Topography; for assistant data to classify in the Remote Sensing; as basic data in the GIS, for analysis and layout actuality of using soil, for disaster prediction; for navigation, guiding missile in the military affairs.

美国麻省理工学院Miller教授为了高速公路的自动设计于1956年提出了数字地面模型的概念后，DEM被用于各种线路的设计及各种工程的面积、体积、坡度的计算，任意两点间可视性判断及绘制任意断面图；在测绘中被用于绘制等高线、坡度坡向图、立体透视图，制作正射影像图与地图的修测；在遥感中可作为分类的辅助数据；它是地理信息系统的基础数据，可用于土地利用现状的分析、合理规划及洪水险情预报等；在军事上可用于导航及导弹制导；在工业上可利用数字表面模型DSM或数字物体模型绘制出表面结构复杂的物体的形状[2]。
