By analyzing the calculated baryon number susceptibility ratios${\chi_{1}^{B}}/{\chi_{2}^{B}}$ and ${\chi_{3}^{B}}/{\chi_{1}^{B}}$ intwo-flavor system via the Dyson-Schwinger equation approach of QCD, wedetermine the chemical freeze-out temperature and baryon chemical potential incases of both thermodynamic limit and finite size. We calculate thecenter-of-mass energy dependence of the ${\chi_{4}^{B}}/{\chi_{2}^{B}}\,(\kappa \sigma^{2})$ at the freeze-out line and find an excellent agreementwith experimental data in $\sqrt{S_{NN}^{}} \geq 19.6\,$GeV region when takinginto account the finite size effect. Our calculations indicate that the $\kappa\sigma^{2}$ exhibits a non-monotonic behavior in lower collision energy region.
