摘要
一、引言关于单积分的求科公式及其误差估计式,研究的是较为深入。对于重积分的求积公式及其误差估计式的研究相比之下就显得很少。数学手册上给出了几个重积分的求积公式,严格说来它们只是几个十分特殊的例子,不能称为重积分的求积公式。
This paper deals with bivariate linear. quadratic and cubic interpolatingsplines of the bivarate function f(x,y) on the net of right triangualr partition of aribiraryclosed rigion on a plane and its error estimations. Then, as an application of these splines,in this paper several quadrature formulas of the double integral are derived using abovementioned splines. And the error estimations of these quadrature formulas are given too.
