Abstract：
It is shown by both theoretical analysis and Monte Carlo simulation that using correlation integral instead of factorial moments in the investigation of intermittency phenomena will change the anomalous scaling behaviour in the decreasing of rapidity bin. It is pointed out that the correlation lintegral and. factorial moments probably bin. It is pointed out.that the correlation integral and factorial moments probably reflect different physical aspects. In order to eliminate the artificial factor in bindivision, a method of randomly moving the starting point of bin-division in the investigation of factorial moments is proposed. It is also shown that the spiky events have important contribution to the intermittency indices.
