摘　　要：通过对一类考研试题的探究,得出若已知n阶实对称矩阵A的s个互异特征值,则A可由它的任意s-1个特征子空间唯一确定这样一个结论。Let A be a real symmetric matrix with s distinct characteristic values. In this paper, we obtain that A is uniquely determined by its arbitrary s-1 characteristic subspaces through the exploration on one type of the examinations for post graduates.

关 键 词：实对称矩阵 特征值 特征子空间
