如果系数1，然后我们称之为积极的求积公式。

2·Therefore the generalized numerical quadrature formula with the single node is deduced naturally.

而且，由此自然地推导出单节点数值积分公式。

3·Theorem 2 There exists uniquely an quasi-Gaussian quadrature formula, which is just the Gaussian quadrature formula;

定理2存在着一个独特的准高斯求积公式，这是刚刚高斯求积公式；

4·We introduced a new and simple proof of the classical SIMPSON quadrature formula which is frequently applied in calculating definite integrals and best estimation of error is obtained.

对于定积分近似计算中常使用的经典SIMPSON求积公式介绍一种新的简洁的证明方法并给出误差的最佳估计。
