These extensions lead to generalized Gaussian quadrature formulas which have high algebraic precision.

这一推广导出了具有高阶代数精度的广义高斯求积公式.

As the number of the Gaussian quadrature points is increased, the accuracy of the integration increases.

当高斯点的个数增加时，积分的精度就增加。

The Gaussian quadrature is a highly accurate numerical integrator and yields results that outperform those from the prism method and the FFT method.

高斯积分法是一个高精度的数值积分方法，它的计算结果精度胜过角柱体法与快速傅利叶法。
