摘　　要：根据曲线在造型设计上需求,一组拟五次Said-Ball基函数被构造出来了,本文详细地讨论了拟五次Said-Ball基函数的性质。定义了由拟五次Said-Ball基函数生成拟五次Said-Ball曲线,讨论了相邻的两段拟五次Said-Ball曲线的拼接的条件,曲线的形状可以调整,实例说明所构造的曲线是实用的。According to the demand of curve modeling design,a group of quasi quintic Said-ball basis functions are constructed.In this paper,properties of the quasi quintic Said-ball basis functions are discussed in detail,and the quasi quintic Said-ball curves generated by the basis functions are defined.Conditions for splicing two adjacent quasi quintic Said-ball curves are discussed and the shape of the curves could be adjusted.Examples indicate that the constructed curves are practical.

关 键 词：造型设计 形状参数 曲线拼接
