To solve this problem, that is, the choke point in the process of orientating a bourgeois periodical, this thesis offers the following methods: First, to distinct the range of orientation. This is not only simply choose the right readers communities. Instead, it is in a huge and complicated system, to choose the right types of readers, then under the premise that these people are in a condition of ceaseless changing and developing, determine the right publishing channel, and finally send the right information to these people. This is a dynamic process, resembling the logic clue of satisfactory theory. Therefore, this would be proved in this thesis by the way of counterevidence.

因此，本论文所进行的有关中产阶层期刊市场定位瓶颈问题的研究，就是按照下列框架展开论证：一、在确立核心概念的基础上，明确研究对象，并以文化发展观和传播学的经典理论——使用与满足理论，建构受众细分时代中国中产阶层期刊市场的描述框架，由此呈现问题。

This article focuses on the line-line, line-region and region-region topological relations algorithm, which come down to the same question: whether there are intersections between line and line. The sweep-line algorithm was studied by many people, but has some deficiencies to be improved, in order to handle some special cases and increase program efficiency. My works as follows: rectangular envelope to reduce executive times , vector cross multiplication to determine intersection between line and line, coordinates and slope method to deal with some special cases. C program examples are showed together.(5) Finally, to prove capability and efficiency of the model and calculation method, some test systems are developed. For example, complex spatial topological relation query, parcels' exact area with the area of linear object reduced in land use, quality inspection to cadastral data according to topological rule, spatio-temporal change query of cadastral data.

将线线、线面、面面之间的拓扑关系实现的算法归结为线与线之间求交的基本问题；为处理一些特殊的拓扑关系情况，提高扫描线算法的效率，探讨了包络矩形粗滤、判断线线是否相交的矢量叉乘法、线节点重合或共线的斜率坐标判断法等改进方法；同时还设计了一种新的节点微小圆求交的算法，可应用于图斑与线状地物细分拓扑关系及地类面积的计算；（5）本文设计了实验系统，包括复杂对象的拓扑关系表达与计算程序、图斑地类面积的计算程序、基于空间拓扑关系规则的地籍数据库质量检查功能，以及时空拓扑关系和变化语义分析等原型，验证了拓扑关系表达模型和计算方法的可行性和实用性。
