摘要：
The periodically forced Fokker-Planck equation of a one-variable system in a bistable potential is solved perturbatively. It is shown that the solution tends to a unique asymptotic distribution, whose parametric dependence on the diffusion coefficient as well as on the strength and phase of the forcing are explicitly exhibited. The results are further corroborated by numerical solutions and by an exact analytic solution for a simple model of linear drift. © 1990.
