摘要
给出了一类五阶常微分方程所有解一致有界和当t→∞时收敛于零的充分条件· 得到的结果包含并改善了Abou_El_Ela和Sadek1999年关于非自治微分方程渐近解的结果·
The sufficient conditions are given for all solutions of certain non_autonomous differential equation to be uniformly bounded and convergence to zero as t→∞.The result given includes and improves that result obtained by Abou_El_Ela & Sadek.
