摘　　要：研究一类具分布时滞的三阶非线性中立型阻尼泛函微分方程.利用Philos方法,建立了保证该类方程的一切解振动或者收敛于零的若干新的充分条件,推广和改进了最近文献的结果.The oscillation of third-order nonlinear neutral damped functlonal diffterential equations, distributed delays is studied. By using Philos＇ method, some new sufficient conditions which insure that any solution of this equation oscillates or converges to zero are established. The corresponding results in known literature are extended and improved.
