在晶格气体模型的框架中研究了12 9Xe系统在破裂过程中的热力学性质和轻粒子发射性质随核温度和系统的冻结密度的变化规律 .计算发现在不同的冻结密度下 ,12 9Xe破裂过程的物理观测量呈现了不同的温度相关性 .在这种情况下 ,核物质液气相变发生时的临界温度强烈地依赖于系统的冻结密度 .当激发能代替温度作为一个自变量时 ,临界激发能将不再灵敏地依赖于系统的冻结密度 .除此之外 ,由于不同冻结密度而引起的不同粒子发射产额的温度相关性 ,也随着激发能的应用 ,出现了几乎一致的激发能依赖性 .从这些结果中可以认为 ,激发能可以作为一个控制核破裂的基本物理量和标度量
In the framework of the lattice gas model, the thermodynamic properties of 12 9Xe system and the variation of the emission properties of light-emitting particles with the temperature of the core and the freezing density of the system were investigated. It was found that under different freezing densities, the 12 9Xe rupture process The physical observations show different temperature dependencies, in which case the critical temperature at which liquid-gas phase transition of nuclear matter occurs depends strongly on the freezing density of the system.When the excitation energy replaces temperature as an independent variable, the critical excitation Can no longer depend critically on the frozen density of the system.In addition, the temperature dependence of the different particle emission yields due to the different freezing densities, along with the application of the excitation energy, shows almost identical excitation energy From these results, it can be considered that the excitation energy can be used as a basic physical quantity and a standard quantity for controlling nuclear rupture
