| 中文摘要: |
| 文中首先得到一阶中立型时滞微分方程所有解振动的一个新的充分条件,
然后把这个结果推广到一个一般的中立型微分方程,改进了文献中许多已知结果. |
| 英文摘要: |
| In this paper, a new suffcient condition for the oscillation of all solutions of first order neutral delay differential equations is first obtained. Secondly,the result is extended to a general neutral differendial equation,and many known results in the literature are improved. |
