摘要
讨论了当积分区间的长度趋向于零时Gauss Legendre求积公式的余项的中介点ξ的变化的渐近性质,并提出了对应于该公式的校正公式,它有较高的代数精度。
Gives asymptotic properties for the location of medium point ξ to contain within remainder term is determined when the length of integral interval tends to zero. The correct formula with respect to the formula is presented, it has higher algebraic accuracy.
