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。

Space curve is one of the basic elements in geometric modeling, and its effective representation is the basis of modeling. Parametric representation based on features is a kind of high-level representation including semantic information. In Chapter 4, para- metric representations based on features for free form space curve are investigated, and a parametric model for the loop of plain knitted fabric is established, in which 5 parameters with practical meanings are used to represent the shape of a loop and the relationship between loops. A new shrinkage prediction method for knitted fabric are proposed based on the parametric representation and energy minimizing. Experimental results on some plain knitted fabrics illustrate the feasibility of the proposed method.

空间曲线是造型中最基本的几何元素之一，对其有效的表示是造型的基础，而特征参数化表示是其中一种包含语义信息的高层次表示，本文对空间自由曲线的特征参数化表示进行研究，建立了一种针织物线圈的特征参数化几何模型，采用5个具有实际意义的参数表示织物线圈的几何形状及线圈之间的位置关系，并将该模型与能量极小化的方法相结合，得到了一种能较好地预测针织物缩水率的新模型，对随机选取的一些针织布缩水预测实验表明了算法的可行性。
