摘要
基于五次叠样条本文获得了一个光滑函数的数值积分公式，它的精度比使用单一五次样条获得的数值积分公式要高二阶，它的误差约为复化梯形公式三次外推结果误差的１／２８６．
In this paper,we obtained a numerical integration formula for smooth function using the quintic spline-on-spline technique. Calculation accuracy of this method is higher two order than numerical integration formula using a single quintic spline.The rate of the er rors of this method and the extrapolation of the trapezoidal rule is about 1/286.
