Abstract：
The pseudorapidity distributions of charged particle multiplicity 4-24 produced in pp collision at 400GeV/ chave been measured by using the LEBC films which were offered by the CERN NA27 Collaboration. The average maximum charged particle density in a selected pseudorapidity window (△ η=0.5 or 0.1) rises linearly with the charged particle multiplicity. There is a trend for the probability distributions of the maximum particle density at large nto widen and flatten. But the event that the maximum particle density is anomalously high was not observed.
