  Since the baryon-number susceptibilities are correlated with the cumulant of
baryon-number fluctuations in experiments, we do calculations of the
susceptibilities and compare them with the experimental fluctuation data under
the framework of the Dyson-Schwinger equations (DSEs) approach. We compare our
results with lattice QCD and experimental data at RHIC. The fitness of the
results indicates that under the framework of DSEs, we can deal with the
problems of heavy ion collisions properly.
