Abstract：
High-multiplicity and large-fluctuation data for nucleus-nucleus collision processes at different energy-ranges are analyzed in an event-by-event manner, by using model-independent statistical methods. The result of the analyses obtained by using CERN-EMU01(³²S on fixed Au target at 200A GeV) data and that obtained by using RHIC-STAR(Au+Au at \sqrt{s_{_{\rm NN}}}=200GeV) data are compared with each other; they are also compared with the existing result obtained by using JACEE-data at cosmic-ray energies. The results of such comparison are presented and discussed.
