摘　　要：研究了用3次均匀有理样条曲线光顺拟合一组平面点列的问题,其中光顺性由曲线的能量积分与扰动量的加权平均来确定.In this paper, a new Bspline modeling method which fairly fits 3D data points while at the same time strictly interpolates some of them was presented. This method obviously has some practical applications in designing many parts of mechanical productions.
