摘　　要：本文利用数值模拟技术，对色噪声和周期激励驱动下粒子在双势讲中的过阻尼运动进行研究，获得了周期形式的非平稳概率流，发现它们与白噪声作用时的概率流有相同的拓朴结构。N this paper, numerical simulation technique was applied to study the over--damped motion of panical in the double-well potential --ax2/2+bx4/4 which was subject to both pexiodic and colored noise forcing. The periodic non--stationary probability flow are obtained. We find that the topological structure of these flow in'colores' are the same as those in the 'white' case.
