摘要
本文从Ｆｕｚｚｙ方阵与其截阵在周期和指数上的关系出发，得到了Ｆｕｚｚｙ阵周期与指数的几个性质，并对个别已有结果进行了更为简洁的证明；对可控阵周期的图论特征进行了讨论，指出可控阵的极小强支的周期不大于２，从而可控阵的周期也不大于２。
In this paper, some properties on tile periodicity and index of a fuzzy matrix arestudied by using the relationship of periodicity and index between a fuzzy matrix and its cutsmatrices. And several gotten results are proved more laconically. We discuss the graphiccharacteristics of a controllable fuZZy matrix, indicating the fact that the periodicity of aminimal strong component of a controllable fuzzy matrix isn't greater than 2. So theperiodicity of a controllable matrix isn't greater than 2 either.
