【摘要】 本文在平均场理论框架下用手征破缺模型研究了不同温度区域饱和核物质的热力学性质.改进并推广了Chowdhury等人的结果,通过费米积分的数值积分确认了Chowdhury等处理核物质低温高密度系统近似方法的适用范围为βμ_eff>2.4,给出了（液）-（气）相变临界温度T_c（?）23MeV,并得到核子-反核子等离子体相变区域为T=150～200MeV.更多还原

【Abstract】 The saturating chiral breaking field theory are used to study thermostatic properties of nuclear matter for different regions of temperature in the framework of mean-field theory. The results given by Chowdhury et al. are improved and developed. By using the numerical integration for the Fermi integral, we find the low temperature approximation taken by Chowdhury et al. to be valid only when 尾渭_eff>2.4. The critical temperature T_? for the liquid-gas phase transition is obtained to be about 23MeV and the phase transition of the nucleon-antinucleon plasma is found in the range from T=150MeV to T=200MeV.更多还原
