Abstract：
The fission probability and the mean square deviation of position as a function of time are calculated by solving the Langevin equation directly with a computer generated randon force. The fesults are compared with the results by Weidenmuller et al.which are obtained by solving the Fokker-Plank equation numerically.The method may be easy to easy to extend to multiple dimension cases.
