| In this article,we studied the equation of state and fluctuations of 2+1 flavor low energy effective model within the functional renormalization group(FRG)approach.The Taylor expansions and its convergency of thermodynamic observables,such as pressure,entropy densities,energy densities,within the constraints ofμ_Q=μ_S=0 or n_Q/n_B=0.4,n_S=0,are studied.After rescaling,one finds the low energy effective model results are consistent with lattice QCD results.The Taylor expansions of thermodynamic observables are convergent with (?)_B≤2,some of them,such as pressure,are convergent well with (?)_B≤4. |
