摘　　要：根据某些函数的特性,通过改变单节点数值积分公式中节点的位置,对数值积分中点公式进行了改进,得到两个单节点高精度数值积分公式,由此可以极大的提高近似计算的精度.With the features of functions, the numerical integration formula with a mean point has been improved by improving the location of the point, and the advanced precision formulas with a single point have been abtained, and the precision of the calulation result has been improved.
