Previous graphic display is downloaded from the dedicated Client ActiveX or Java applet to achieve, or raster graphics generated by the server release, only users of graphics and visual information and do not have the flexibility to access and computer graphics to achieve further analysis.

以往的图形显示主要是由客户端下载专用的ActiveX控件或Java Applet来实现，或者由服务器端生成栅格图形后发布，图形对用户而言仅仅是视觉上的信息，不具备对图形实现灵活检索和计算机再分析的能力。

It is found that the internal relation between the wavelet method and multi-scale representation will determine the law by which the graphic information varies following the change of the scale. That work mark a new step towards the successful application of wavelet theory in the automatic map generalization and provide a new basis and mechanism for the multi-scale representation in GIS.

随着二维与三维设计技术的交叉发展，目前的参数化设计主要有两个分支：①面向纯二维的图形参数化，其特点是二维图形为多拓扑环的复杂图形；②面向三维的基于CSG特征造型的参数化，用于拉伸扫描的单拓扑环的二维图形参数化及空间任意曲面的参数化是其特点。

The symbolical, decorative, subjective and formulistic theory and technique are widely applied in modern plane design. The longitudinal and transverse inheritance of the traditional graph is also discussed in the thesis. Modern art design tries to inherit the essence of traditional graph by making use of its form.

传统图形色彩的象征性、装饰性、主观性、程式化的色彩学理论与技术被广泛应用于平面设计中；本文同时讨论了传统图形在平面设计中的纵向与横向的传承，在现代艺术设计中对传统图形取其形、达其意、传其神；中华民族长期以来既创造了浩如烟海的图形精品，也创立了包括哲学思想、构图意蕴、构成法则、色彩学等完整的艺术设计理论体系。

This paper is based upon XiShan Colliery Parent Company .The data of DongQu Mine pit ventilation resistance mensuration is combined. And system theory, graph theory, ventilation network technology and computer technology are utilized. According to the reality of coalmine, we think that graph and database is incorporate in mine ventilation system. So based on this, ventilation system standard graph is founded, the tool of ventilation graph to draw is made, the ventilation network calculation is realized, the outcome of the ventilation network calculation is seen on the screen, and opaquing and inquiring of the road parameters and so on. In addition to mine ventilation drawing-database visual management system is developed.

本文基于西山煤矿总公司东曲矿〖东曲矿矿井通风网络计算机管理系统〗科研项目，结合东曲矿矿井通风阻力测定，运用系统理论、图论、通风网络技术及计算机技术，针对煤矿实际，将矿井通风系统中图形和数据库贯穿为一体，创建了通风系统标准图库并编制了通风图形绘制工具，实现了风网解算和解算结果图形显示及巷道参数的修改、查询等功能，开发了矿井通风图形数据可视化管理系统。

Refers to the relation of graphics to surrounding text, which may wrap around the graphic on one or both sides, be overprinted behind or in front of the graphic, or treat the graphic as a separate paragraph or character.

文字环绕指文字与图形的相对位置关系，文字可以在图形的一侧或者两侧排布，或者从上面或者下面贯穿图形，甚至把图形当作段落或者字符处理。

Nowadays, the development of computer graphics systems tends towards features with much higher quality and high speed . Super-microcomputer system with uni-processor could no longer afford the processing capability in these high-end graphics technology fields. By using supermini even mainframe computer would be too expensive. All these factors limit the new application field of computer graphics.

在目前，计算机图形系统向着高质量和高速度发展过程中，由单处理机组成的超级微计算机系统已不能满足图形技术某些领域对处理能力的需求，而用中、小型以致于大型机实现的图形系统成本高，限制了图形系统的应用。
