1. The methods that represent geometry elements such as line , circle and arc , plan , cylinder , cone and sphere in nurbs form are studied . meanwhile , the calculating process that interpose to nurbs curve and surface are advanced . to the processed surface , the paper brings forward a method to distill its character ( plan , cylinder and sphere ) by the main curvature of surface using its local differential coefficient geometry characteristic
   对nurbs的直线、圆和圆弧、平面、柱面和球面等的表示方法作了理论研究，同时对nurbs曲线曲面的进行插值的计算，插值后的nurbs曲面，利用其表面局部微分几何特性，提出依据曲面的主曲率来提取特征面(平面、柱面和球面)的方法。
