英文摘要：

In this paper, the oscillation for a class of second order nonlinear dynamic equation on time scales with damping term and variable delay was discussed. Using the time scales theory and some necessary analytic techniques, some sufficient conditions for oscillation of the equation were proposed by introducing parameter function and the generalized Riccati transformation. These results improve and generalize some corresponding known results in the literature.
