以半经验的能量密度为基础,利用Fermi-Dirac积分的低温展开,得到了核的状态方程P(S,ρ)。在绝热假定下,采用流体动力学方程,具体研究了不同的热压缩核的动力学演化,特别分析了热能和压缩能对热压缩核稳定性的影响。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.
