文摘Using an aspect of rapidity bins with finite sizes the short-range and longrange behaviors of two-particle correlation, the connection of two particle correlation function with factorial moment and factorial correlator are investigated; and experimental data for 16 O+Em interactions at 14.6, 60 and 200 A GeV and 32 S+197Au interactions at 200A GeV are analyzed. It is shown that the bin-average of two-particle correlation function can naturally give a coordinate description of dynamical fluctuation such as the second order factorial moment <F2> and 1+1 order factorial correlator <F1,1>.
