摘　　要：本文讨论时标上的变时滞二维动态系统的解的振动性质,我们得到的振动准则既适用于变时滞二维动态系统,也适用于变时滞二维微分系统和差分系统及某些二阶时滞动态方程.In this paper,we study a problem of oscillation for two-dimensional delay dynamic systems on time scales. Our results not only unify the oscillation of two-dimensional delay differential systems on time scales, but also include the oscillation results for delay differential systems and provide new oscillation criteria for delay difference systems.
