摘　　要：讨论了一类二阶非线性摄动微分方程解的振动性和渐近性,得到了该方程振动与渐近的一个充分条件,推广了现有文献的相关结论.Oscillatory and asymptotic behavior for solutions of the second order non-linear differential equation are considered in this paper. New oscillation criteria are established and the results obtained are new and extend the known results in related literature.
