论文摘要
我们证明，两个等级第二的基本阿贝尔组的直接乘积，以及循环级别阶阶和一个平方自由订单的循环群的直接乘积是dci群体。后者是对穆齐丘克对循环群的结果的概括（J.Combin。理论Ser。A，1995）。
We prove that the direct product of two coprime order elementary abelian groups of rank two, as well as the direct product of a cyclic group of prime order and a cyclic group of square free order are DCI-groups. The latter is a generalization of Muzychuk's result on cyclic groups (J. Combin. Theory Ser. A, 1995).
