| 摘 要： | 论述了在拟合逼近膜结构不规则区域的曲面中，如何通过自动剖分离散的数据点得到１个初始的三角形集，对初始的三角剖分进行重新组合分析，以得到适宜的三角形，从而构成１张较好的曲面。

| Abstract: | A preliminary triangular set is obtained in the process of fitting and approximat-ing irregular curved surfaces of membrane structure by subdividing discrete data point auto-matically. Then, the preliminary triangulation is combinatorially analysed to get optimal tri-angle and construct a better curved surface. |
