摘要
讨论了超定线性方程组的切比晓夫解的残差与最小二乘解的残差之间的关系，研究了离散切比晓夫逼近的偏差点性质，同时推翻了文献［２］中的一个错误论断．
This paper discusses the relationship between error vectors resulted from mini-max solution and least square solution of an overdetermined linear equation.Some interesting properties of maxi-deviation points in the sense of Tchebycheff approximation are given.
