具有正负系数的—阶时滞微分方程解的渐近性

Asymptotic Behaviour of Solutions of First Order Delay Defferential Equations with Positive and Negative Coefficients

考虑具有正负系数的—阶时滞微分方程，获得了它的每一解当ｔ→∞时趋于零的充分条件．

The first order delay differential equations are considered.We obtain thesufficient conditions for every solution tending to zero as t→∞.
