摘要
数值积分中的高斯型积分适用范围广，代数精度高．资料中只给出一般的高斯求积公式，而对公式中的系数Ａｋ未进行深入研究．本文利用正交多项式的性质及代数精度，深入研究公式中的系数Ａｋ的特性及计算方法，并给出了公式及证明．
Based on the characterise of orthogonal polynomial and algebraic precision, the coefficients A k of Gaussian integral formula and calculation were discussed in detail, the calculation formulae of coefficients and their proof were given. The obtained result is useful to application of Gaussian integral formula.
