摘要
本文对文献[1]中的正态分布近似式给出了四点平均补偿,从而大大提高了精度,并克服了文献[2]中的缺点。
In this paper the author proposes a mean compensation algorithm based on the principle of replacement of integral region[1,3]. Tie approximate formulas
m=l, 2,……
in relation to probability integral
are given. These approximations are better than Wang Jingong's[1] formulas. They remedy a defect of Yang Ziqiang's formulas[2].
