本文讨论了非均匀三角剖分上的二次Powell-Sabin样条空间中拟插值的构造问题。提出了最佳逼近阶的拟插值，并给出了数值试验。
In this paper we address the problem of constructing quasi-interpolants in the space of quadratic Powell-Sabin splines on nonuniform triangulations. Quasi-interpolants of optimal approximation order are proposed and numerical tests are presented.
