The calculations are done for the quark-gluon phase before hadronization, the pion gas, the resonance pion gas from $\\rho$ and $\\omega$ decays and so on. The simulations of the charge fluctuation show that the discrepancy exists between the dynamic model and the thermal model for a pion gas and a resonance pion gas from $\\rho$ and $\\omega$ decays while the simulated charge fluctuation of the quark-gluon phase is close to the thermal model prediction.
