Automatic generate of 3D dimension model based on the function semantics;

The motion constraint of mechanical product in terms of the definition of function unit was abstractly expressed,and a new scheme of evolutionary modeling for mechanism motion based on function semantics was proposed.

A new representation method of mechanism motion model for conceptual design based on “the trinity” of function semantics is put forward, and the motion transform constraint and motion connection constraint carried by function semantics are described.

Disassembling a part into the features of basic entity(FBE),the dimensional models were gained by analyzing the change of the functional semantics of dimension during FBE s combination.

The method makes possible the automatic inspection of the consistency between the geometry descriptions and functional semantics of the features in the complete design history during the process of parts design.

In this dissertation, on the basis of the analysis of the dimension effect of engineering drawings, a dimension model based on functional semantics is advanced.

Comparison between the form position and semantic function of Chinese-English affix;

It points out that their semantic functions are measured by the action or the time and the space of the central matters with action, and this structure is a method to indicate Chinese predicator number classifier feature, so it is declaration but not reference.

It points out that such deviated collocation is creative collocation with strong semantic function based on figure of speeches.

On semantic functions and usages of pronunciation and intonation

From,one of the most important prepositions,forms vast multitudes of idiomatic phrases with other words,which contributes to its rich semantic functions.

In the paper three semantic functions and their inherent relations and developmental connections of the frequently used adverb "dao(倒)" in Chinese are discussed.
