摘要
利用体上矩阵的理论,证明了Cochran定理在任意体上的推广中的条件是充分的,并得到另一个新的结果,从而发展了这一推广的结果。
By using the theory of matrices over skew field,it is proved that the conditions in 'the generalization of Cochran's theorem over any skew field' is sufficient, and a new result is also obtained. The result of this generalization is developed.
