有理数域 meaning in English

field of rationals
rational number field
region of rationality

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。
