Abstract：
A variational method is developed to solve Fokker-Planck (F-P) equation. One dimensional fission probability is calculated and compared with other methods. The relation of F-P equation and Smoluchowski equation is discussed in light of thismethod, which gaves the way to derive the multi-dimensional Smoluchowski equation with varying mass and viscosity and to solve more complicated F-P equations.
