摘要
本文得到了保形Ｃ１二次样条插值函数存在的充分必要条件，并给出了一种通过插入一些新的结点来构造保形Ｃ１分段二次样条插值函数的简单算法．
n this paper, a necessary and sufficient condition for constructing a shape preserving C1 quadratic interpolation spline function is given and a new spline method for constructing shape preserving C1 piecewise quadratic interpolation functions is obtained by means of insetting some new nodes.
