The least square polynomial Q n ( x) is introduced, and an interpolation polynomial for function is made with its zeros as nodes, and a kind of quadrature formula for singular integrals is obtained. The Gauss type quadrature formula is its special form. 引进最小二乘多项式簇{Qn(x)},由Qn(x)的零点出发作插值多项式,得到了奇异积分的一类求积公式,它的特殊形式为Gauss型求积公式。
