摘要
本文研究非线模型中内、外噪音的统一描述.通过对噪音的实现求平均,得到广义福克-普朗克方程(GFPE).发现从某一阶矩开始,出现内、外噪音的耦合效应.文中还对Verhulst模型进行了具体的讨论.
A unified description of nonlinear systems in which the internal and external noises are simultaneously considered is presented. A generalized Fokker-Planck equation is obtained and from the moment equation derived, the coupled effect between the internal and external noises is found.
