Abstract：
In this paper, the two dimensional Fokker-Planck Equation is exactly solved by means of the numerical method. The velocity distribution at the saddle point, the second moments of the coordinate and velocity, the time development of the nuclear fission rate are studied. The maximum of the fission rate at a certain viscosity is exhibited by studying the dependence of the fission rate on the nuclear viscosity.
