Study on Conceptual Structure and Tolerance Design Method in Product Reverse Engineering;

determining the number,the style and the relationship of function surface is the key of conceptual structure.

A conceptual structure modelling method based on coupling semantics was presented to resolve the problem of uniform representation of geometrical element and design intent attached to the geometrical element in part structure.

Strengthening and applying the concept of the structure in the graduate design of the civil engineering specialty;

According to the demands of analysing knowledge inquiry about"questions"and"methods"in the scientific research work,the concept structure about"the research question"and"the technical method"in a paper is proposed.

concept structure and its relevant language structure while investigating the systematic character of a terminology, so as to endow terms with motivation; thus, they are able, through the language forms of terms, to reveal the characteristics of the concepts named by means of terms and the relationships betwee.

Firstly, it analyzed concept image, concept structure, concept field and concept system, which related to mathematical concept representation.

The structure concept lattice is the logical storage of semantic structure of documents, and the content concept lattice is used to store content information of documents.
