摘要
本文通过揭示某些由完全椭圆积分定义的函数之单调性与凹凸性，研究Spanier与Oldham给出的椭圆积分的4个近似表达式，导出完全棉圆积分的精确不等式。
In this paper,the author studies Spanier and Oldham's four approximations for complete elliptic integrals by showing monotoneity and concavity of certain cOmbinations of complete elliptic integrals,and derives sharp functional inequalities for these special functions.
