摘　　要：本文主要研究了非线性随机Pantograph微分方程,讨论了其零解的均方渐近稳定性并给出了零解均方渐近稳定的充分条件.在本文的第三部分,我们将随机θ-方法应用于这类问题,获得了数值解均方渐近稳定条件.This paper studies mean-square asymptotic stability of the zero solution of initial problems of a general class of stochastic pantograph differential equation. The sufficient conditions of mean-square asymptotic stability of the zero solution are derived. In the third section, numerical methods based on θ- methods are suggested and mean-square asymptotic stability conditions for the presented methods are derived.
