Abstract：
The two different normalization schemes of factorial moments are alalyzed carefully.It is found that in both the cases of fixed multiplicity and of intermittency independent of multiplicity,the intermittency indexes obtained from these two normalization schemes are equal to each other.In the case of non-fixed multiplicity and intermittency depending on multiplicity,the formulae expressing the intermittency indexes from the two different normalization schemes in terms of the dynamical index are given.The experimentally observed dependency of intermittency degree on transverse momentum cut is fully recovered by means of the assumption that intermittency degree depends on average transverse momentum per event.It confirms importance of the dependency of intermittency on average momentum.
