【正】 The conditional moments of the charge distributions of the projectile frag-ments in <sup>16</sup>O and <sup>32</sup>S fragmentation behaviour are obtained by using a partition meth-od.The logarithmic correlations between the conditional moments are observed,Thecalculated results are in agreement with the experimental data of 3.7 and 200GeV N <sup>16</sup>O-emulsion and 200 GeV/N <sup>32</sup>S-emulsion interactions.
