摘　　要：讨论时标上的二维时滞动态系统的解的振动性质,得到的振动准则既适用于二维时滞微分系统和差分系统,也适用于某些二阶时滞动态方程.In this paper, a problem of oscillation for two-dimensional delay dynamic systems on time scales is studied. The results not only unify the oscillation of two- dimensional delay differential systems and delay difference systems, but also include the oscillation results for delay differential systems and provide new oscillation criteria for delay difference systems.
