| 摘 要： | 传统的边界表示通常是一种数据结构，缺少一种代数形式来表示几何模型的不同抽象层次和相似性。本文用面边、边点关联矩阵来表示模型边界及其可变性层次，研究了它的同态和相似，并用于特征造型，重点介绍了形状特征的形式化定义。

| Abstract: | Conventional boundary models without a well formalization can hardly represent the model hierarchy and similarity. This paper represents the boundaries of geometric models and their variation hierarchy using improved face-edge and edge-vertex incidence matrices,and studies the isomorphism and analogy of boundary models. The applications of this model in form feature definition are introduced. |
