摘要
有理数去逼近代数数中如何确定常数使逼近效果较好是研究此类问题的关键之一。本文讨论特殊的二次代数数ξ的有理逼近，确定出了ξ的常教c＝c（ξ）。主要结果为：对任意的整教对（p，q）（q＞0）．不等式恒成立，并且给出了等号成立的条件。
It is one of the key problems in rational approximation to algebraic number and reach much higher accuracy. In this paper the author discussed this problem in case of endless square root number, obtained the coefficient c(ξ), the main result obtained here read as the following:For any pair of integer (p,q) (q>0), there holds inequality:
