Abstract：
The problem of the nuclear fission rate is studied from the point of view of Brownian motion. The Fokker-Plank equation is solved by means of the rate ei-genvalue method. The viscosity tensors, the inertia coefficients and the temperature are functions of nuclear deformation. Their effects on the fission rate are also stu-died.
