Abstract：
Using a hadron and string cascade model,JPCIAE,and the corresponding Monte Carlo events generator,the behavior of the charged particle ratio event-by-event fluctuations in subsystem depending on energy,centrality,resonance decay and rapidity interval was investigated for Pb+Pb collisions at SPS and ALICE energies,and for Au+Au collisions at RHIC energies. The model results of charged particle ratio event-by-event fluctuations as a function of the rapidity interval in Pb+Pb collisions at SPS energies were comparable with the preliminary NA49 data. It turned out that the charged particle ratio fluctuation has no strong energy,centrality,resonance decay and rapidity interval dependences.
