曲面

An algorithm of line scanning is addressed to identify the boundary of projectable surface.

提出了可投影曲面数据边界识别的线扫描算法。

At first, it may be a good idea to select the numbers of control points from the boundary curves. If the surface is not adequate, this number can be increased.

起初，从边界曲线上选择控制点可能是个比较好的主意，但如果曲面不够的话，这个数量可能会增加。

A method of warp and weft scanning was proposed to automatically extract the boundary of single value surface.

复杂曲面逆向工程的首要任务是通过各种测量途径得到实物表面的数字化信息。不同的测量手段为逆向工程CAD建模提供了不同的数据来源。

This study presents the investigating of microchannels flow. It is divided into two parts, the flow characteristics of micro venturi and the performance of straight-walled and curved-walled micro nozzle/diffuser respectively. The experimental results are also compared with the simulation results whereby we can observe the flow field in micro venturi and discuss the bounder effect of micro nozzle/diffuser.

本文主要是针对微喷嘴的空气流场进行研究与探讨，研究分为两部分进行，分别是探讨微文氏管的流力特性及曲面微喷嘴边界对流力效能的影响，并将实验结果与CFD软体的分析结果相互比较，藉以观察微文氏管内之流场分布并探讨微喷嘴较佳之流力性能。
