摘要
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.
