We present analytical results of the equation of state (EOS) described by a model of thermal quark mass and magnetic potential term introduced in Polyakov–Nambu–Jona–Lasinio (PNJL) model for two-flavour quarks. Under the influence of thermal quark mass and magnetic field term in the potential, the calculated results of EOS using the model are enhanced in a good pattern up to the temperature $$T=2.2T_{c} $$ T = 2.2 T c MeV and can follow result similar to the unmagnetised field when the temperature is increased beyond $$T=2.2T_{c}$$ T = 2.2 T c MeV. The result shows that the thermodynamic behaviour agrees well with the standard properties of quantum chromodynamics (QCD) thermodynamics and enhance the result up to $$2.2T_{c}$$ 2.2 T c from the earlier predicted results and show the same behaviour beyond $$2.2T_{c}~$$ 2.2 T c MeV.

PNJL模型在热质量和磁场影响下的状态方程

我们展示了由热夸克质量和磁势项模型描述的状态方程 (EOS) 的分析结果，该模型在 Polyakov-Nambu-Jona-Lasinio (PNJL) 模型中引入，用于双味夸克。在势中的热夸克质量和磁场项的影响下，使用该模型的 EOS 计算结果以良好的模式增强到温度 $$T=2.2T_{c} $$T = 2.2 T c MeV当温度升高超过 $$T=2.2T_{c}$$ T = 2.2 T c MeV 时，可以遵循类似于未磁场的结果。结果表明，热力学行为与量子色动力学 (QCD) 热力学的标准性质非常吻合，并将结果从早期的预测结果提高到 $$2.2T_{c}$$$2.2 T c，并且在 $$2.2 之后表现出相同的行为T_{c}~$$ 2.2 T c MeV。
