Abstract：
The event-space moments C_p,q(M) have been calculated using the method of single-event factorial moments. Comparing this with the calculated results for the pure statistical fluctuations Monte-Carlo event sample, the variations of the moments C_p,q(M) with M are caused dominantly by the statistical fluctuation. The erraticity analysis of the pseudorapidity gaps is performed for the NA27 data. The entropy-like quantities S_q and Σ_q are calculated. It is found that S_q and Σ_q deviate significantly from 1. S_q and ∑_q versus q have exponential behavior. FRITIOF simulation can reproduce the scaling behavior, but the deviations of the values from the experimental data are rather large.
