利用MapInfo MapX提供的OCX控件和MapX基本控件分析函数，可实现基于MapInfo的城市道路网网络拓扑结构自动生成。

Segmentation and extraction of the target feature points from the unregistered, noisy data set of human body scanning and measuring are discussed. We have fitted the noise scanned data line with KS principal curve, which is based on the K-means theory. The crossing zero of curvature was used to segment and estimate the position of target feature points. And optimization scheme named variable fuzzy partition is also presented to improve the searching for local feature area.

使用基于K-means思想的KS主曲线算法，对国家人体尺寸测量工作中产生的带噪声扫描线数据集合进行非线性拟合，并依据曲率分布特征提出对目标特征点空间位置进行模糊分区估计的方法；同时提出了变量化模糊分区的优化策略，大幅度地提高了局部特征区域搜索的效率。

By some results of Minor Theorem, we prove the crossing numbers of some circular graphs C(10,4), C(9,3), C(8,3) on the projective plane.

利用C.Thomassen在大边宽嵌入方面的工作，得到了局部大边宽嵌入图的一些性质，再利用线性代数的知识，证明了在局部大边宽条件下存在多项式时间算法可以找到一个图的最短可收缩圈。
