We got the standard form of nonsingular matrix over the finite field by means of BN pair decomposition under the similarity transformation of the permutationmatrix.
利用有限域上一般线性群的BN对分解，给出有限域上的可逆矩阵在置换阵相似变换下的标准形。

Applying permutationmatrix, the association and the system isomorphism between contractual relationship modeling in theory and its operation in practice were verified.
采用置换矩阵，验证了契约关系模型理论构建与现实运作间的关联关系及系统的同构性。
