Using a different method from [1], we extend the result in [1] in two ways: the order of the matrices is extended from 2 to that of arbitrary, the base field of the matrices is extended from Q to any linerable fields of characteristic not 2.

• 摘要用与[1]不同的方法，把文[1]的结论作两方面的推广，其一是把矩阵的阶数从2推广到任意，其二是把有理数域推广到任意特征不是2的可线性化的域。
