拓扑元素的命名机制研究综述

A Research Summary of Persistent Naming Problem for Topological Entities

在基于历史的参数化特征造型系统中,拓扑元素的命名和特征模型重新生成时拓扑元素的正确辨识是一个关键问题。此文基于参数化系统的模型表示方法,探讨了拓扑元素永久命名问题,分析了解决该问题的4个基本条件及其内在关系,将拓扑元素永久命名问题分为唯一命名及其辨识问题和模型重建阶段拓扑结构发生改变时的语义辨识问题2个层面展开研究,并对其他相关研究中的名字问题进行了概述。

To correctly identify topological entities by naming the re-evaluation of the model is one of the fundamental issues In historybased parametric feature modeling systems. This paper is based on the expression of the parametric feature modeling systems. It has analyze 4 basic conditions to solve the persistent topological naming problem,and their internal relationships. There are 2 categories in the persistent naming problem:uniquely name and retrieve topological entities,and how to retrieve topological entities as the topological structure is changed during the re-evaluation process. It also studied to other name question to carry on the outline related.
