The main contributions of the dissertation are concluded as follows: 1 A mathematical basis of the exchange of product data----the Set-based model mapping is established. The shape model mapping, such as the 1: 1, 1: n and n: n topological and geometrical mapping, is especially analyzed.

总结下来，论文做出了以下几个方面贡献：(1)建立了产品数据交换的数学理论基础——基于集合的模型映射，重点研究了在产品数据模型映射中具有代表性的形状模型映射，给出了一到一、一到多和多到多的拓扑几何映射分类。

A method of the surface combination based on classification or Euler Operation and the computation of the surface boundaries of a surface is offered to finish the geometry mapping of surfaces between half-edge model and the closed_shell branch of manifold surface model. Moreover, the concepts of conformal-shape geometrical mapping and topological mapping are given. The bi-directional conformal-shape topological mapping between half-edge model and the closed_shell branch of manifold surface model is proved.

A man cannot tell whether Apelles, or Albert Durer, were the more trifler;whereof the one, would make a personage by geometrical proportions; the other, by taking the best parts out of divers faces, to make one excellent. Such personages, I think, would please nobody, but the painter that made them.

曾经有两位画家--阿皮雷斯和艾伯特丢勒滑稽地认为，可以按照几何比例，或者通过摄取不同人身上最美的特点，用画合成一张最完美的人像其实像这样画出来的美人，恐怕只表现了画家本人的某种偏爱。
