这些求积公式都是基于正交有理函数的插值型求积公式,它们的求积系数都非负,从而是数值稳定的。
These quadrature formulas are all interpolation quadrature formulas based on orthogonal rational functions , and their coefficients are nonnegative .

本文推广了中的结果,对于三维问题,利用多元插值和边界型求积公式给出边界积分方程一种新的数值解法。
In this paper , we generalized the results in ( 1 ), using the multivariate interpolation boundary-type quadrature formulas , we gave a new numerical solutions for three dimension problems .
