| Abstract: | By using Monte Carlo Method,the character istics of a bistable dyanamicssystem under the influence of periodic and noise force are analyzed.The period non-station-ary probability and the joint probability distribution for the system are obtained;Some topo-logical relations among them and potential are found.The jump characteristic and the signalintensity changing with parameter are also discussed. |
