Abstract：
The experments about anomalous scaling of the factorial moments in nuclear-nuclear collisions show that in the final state higher-dimensional phase space,the log-log plot of the factorial moments versus partition number seem to show a stmngly upward bending.Taking into account that the nuclear-nuclear collision is mixture of many elementary collisions,we give an explanation for the above phenomenon.A random cascading model is set up based on the above view point,and the Monte Carlo simulation fits the expedmental phenomenon qualitadvely.The possible application of this effect is discussed.
