Abstract：
According to the non-equilibrium diffusion model of nuclear fission, the fission process can be described by the Fokker-Planck equation (F-P eq.). Through comparison of the exact solution of F-P eq. numerically with the Kramers' stationary results, the success and drawback of Kramers' stationary solution have been pointedout.
