| 摘 要： | ＮＵＲＢＳ曲线、曲面在ＣＡＤ／ＣＡＭ、计算机图形学等领域占有重要的地位。本文通过齐次坐标从代数角度考虑ＮＵＲＢＳ曲线的形状调整,克服了从几何角度考虑的复杂性和有限性,其结果非常有利于翼型设计及气动性能分析。

| Abstract: | NURBS are becoming increasingly widespread in CAD/CAM and Computer Graphics. In this paper, an algebraic procedure for modifying the shape of NURBS curve is presented, which can overeome shortcomings of geometry way. It is convenient for designing the airfoils and studying the penumatic properties of wing. |
