Based on the relationship between the structure and function, a lot of research have been performed on predicting base-pair which is indispensable to the RNA three-dimensional strcutrue. The tools and methods in Combinatorics and Statistics will play important roles in studying linear sequences of biomolocular units . Similarly, we can present the geometric representation of biological sequences and structures. So the genometric topology and group theory are important also.

根据RNA的结构与功能的关系，在预测碱基配对的类型方面进行了相当多的研究，这也是确定RNA三维构象的必不可少的一部分，组合学和统计学的工具和方法在研究生物序列和生物结构上起到了很大的作用，同样我们可以用几何方法来表示生物序列和二级结构，几何拓扑和群论也起到了很大的作用。

Rule-based and reusebased method is adapted in our system to develop applications. Rules are used to define geometric representation of geographic objects, spatial relationships among geographic objects and map design rules. Reusability is realized through object's inheritance and encapsulation. The basic function related to GIS has been implemented in OOGDB's basic class base. Application related function can be implemented in sub-classes of basic classes and some of basic class' function can even be overloaded.

GIS应用系统的开发采用基于规则和基于重用的方法进行，规则用于定义地理对象的几何表示和空间关系以及地图构造的规则等，重用是通过面向对象的继承和封装机制实现的，GIS实现了一个基本的类库，它完成基本的空间处理和操作，用户通过定义这些类的子类重用类库提供的功能，并增加与应用系统有关的特殊功能，用户甚至可以通过重载修改某些类库的功能。

Comparing with general intersecting algorithm, the fuzzy judge tree for finding intersection is constructed in the algorithm based on computation error and representation error of geometric elements.

较之常用算法，本算法针对计算机的计算误差和几何元素在计算机内的表示误差，构造交点模糊判断树，使求两条直线段交点的正确性和可

NURBS has become a representation standard for geometric design systems since 1990.However, it is difficult to model complicated objects with only one NURBS surface patch due to its rectangular domain, and it still suffers from serious limitations in surface stitching.

九十年代以来，NURBS曲线曲面已经成为计算机辅助设计系统的表示标准，由于NURBS曲面定义在矩形域上，难以直接用一张NURBS曲面来整体表示复杂曲面，需要采用分片构造的方法才能达到目的，使得拼接边界处的光滑性也受到了严重限制。

Concept data model of MRGISDM analyses entity's character and relationship. Logic data model designs logical and geometric representation of entity and relathionship; physical data model designs the schema of classification and coding ,orgnization of layers,and physical storage structure.

在MRGISDM概念模型中确定了市政道路中需要表达的要素实体，提取出每个要素实体的属性，并描述出实体之间的关系；MRGISDM逻辑模型则把市政道路实体以及实体之间的关系表达成地理信息系统所能识别的方式，并用UML语言等工具描述成UML逻辑模型图；MRGISDM物理模型从市政道路要素的分类与编码、图层的组织以及物理表结构等几个方面来设计市政道路要素的组织和存储结构。

The features to evaluate the tooth contact quality such as the location of the contact point on the tooth surface, clearance between the meshing tooth surfaces, curve of the transmission error and the path of the contact point are investigated. The accurate geometric representation with non-uniform rational B spline of the worm and the wheel tooth surface is presented then the corresponding program is developed.

根据平面包络环面蜗杆传动的创成方法，建立了包含加工误差的蜗杆和蜗轮的齿面方程，分析了平面包络环面蜗杆传动和平面二次包络环面蜗杆传动的刚性啮合特性如误差对接触点的位置、齿面间隙、传动误差曲线和接触点在齿面上的轨迹的影响。
