摘　　要：讨论了一类三阶非线性脉冲时滞微分方程解的振动性与渐进性,解决了非振动解与其导数的符号关系,所给出的充分条件改进了一些已知结果,并且比相关文献中的条件要简洁且易验证.The oscillatory and asymptotic behaviors of third order nonlinear delay differential equation with impulse were investigated. And the problem of the symbol relationships between the nonoscillation solutions and their derivatives was solved. The obtained sufficient conditions perfect some known results. And these conditions are more succinct and easier to be verified

关 键 词：脉冲时滞微分方程 振动性 渐进性
