Abstract：
The erraticity analysis of the pseudorapidity gaps is performed for the experimental data of multiparticle production in pp collisions at 400GeV/c.The entropy-like quantities S_q and ∑_q which have been proposed by Hwa et al .are calculated. It is found that S_q and ∑_q deviate significantly from 1. The 1nS_q versus q has a quite linear behavior ,but the 1n∑_q versus q has only an approximate linear behavior. The same calculations are performed for the event sample simulated using FRITIOF program. The results have a rather large deviation from experimental data.
