Abstract：
In this paper, we present the centrality, transverse momentum region and rapidity window size dependence of charged particle fluctuation from Relativistic Quantum Molecular Dynamics (RQMD) model. D_Q, Γ_Q and Φ_Q all depend on the rapidity windows we chosen. ν_+－,dyn is a promising observable in experiments, it weakly depends on the acceptance. The beam energy dependence of ν_+－,dyn has been studied to present baseline prediction for net charge fluctuations in experiments.
