摘　　要：在一些有关矩阵运算和证明中,往往把一阶方阵看成是一个数,但在一般的教科书中,并没有给出严格的证明.从等价关系的角度证明了数a与一阶方阵(a)的同一性.In the calculation or certification of the matrix,see order one matrix as a real number sometimes.However,there is no a strict proof of that in the algebra textbooks.Given the proof of the identity between order one matrix and the real number from the view of the equivalence relation ship.

关 键 词：数a 一阶方阵(a) 等价关系 等价类
