一类二阶中立型时滞微分方程的振动性

Oscillations of Second Order Neutral Delay Differential Equations

讨论了一类二阶中立型微分方程的振动性，建立了此类方程解振动或当ｔ→＋∞时趋于０的充分条件。

AbstractWe consider the oscillations of a second neutral delay differention equation. Sufficient condition are given to insure that the solution of these equation are oscillatory or approach to zero when t→+∞.
