Based on a simple energy density and with the help of lowtemperature expansion of Fermi-Dirac integrals, an analytical nuclear equation of state (EOS) P(s, ρ) is obtained. Under the assumption of adiabatic approximation, the time evolution of several hot/compressed nuclei are studied within the hydrodynamical framework. The critical condition of multifragmenta-tion is Particularly analysed.
