【Abstract】 The correlation function method is applied to analyze the fluctuation of the excitation function in the dissipative nuclear reaction. By deriving the energy autocorrelation function, angle correlation function, elements correlation function and isotopic element correlation the characters of the nuclear reaction system in the dissipative reaction varying from the equilibrium to the non equilibrium system are analyzed, and the special role of these method in the study of the dissipative nuclear reactions shown. Experiments of 4.5MeV/u 27 Al+ 27 Al and 102.5MeV 19 F+ 51 V are analyzed by using these function derived in this articles, and the information in dissipative nuclear system, which can be drawn out from this method, is pointed out.更多还原
