摘要：

研究了最小长度方案或广义不确定原理下夸克-胶子等离子体（QGP）状态方程。应用广义不确定原理推导了理想QGP在化学势为零时的热力学性质。我们发现一个显着的效果为GUP长期。在$n_{f}=0$、$n_{f}=2$和$n_{f}=2+1$味的情况下，定量地得到了QCD格点结果的主要特征：能量密度、压强和相互作用测度。令人兴奋的一点是袋压力的大值，特别是在$n_{f}=2+1$味的情况下，这反映了该袋中夸克之间的强相关性，这是已经预期的。我们可以注意到，这是由Stephan-Boltzmann极限所表征的渐近行为将得到满足。

英文摘要：

The quark-gluon plasma (QGP) equation of state within a minimal length scenario or Generalized Uncertainty Principle (GUP) is studied. The Generalized Uncertainty Principle is implemented on deriving the thermodynamics of ideal QGP at a vanishing chemical potential. We find a significant effect for the GUP term. The main features of QCD lattice results were quantitatively achieved in case of $n_{f}=0$, $n_{f}=2$ and $n_{f}=2+1$ flavors for the energy density, the pressure and the interaction measure. The exciting point is the large value of bag pressure especially in case of $n_{f}=2+1$ flavor which reflects the strong correlation between quarks in this bag which is already expected. One can notice that, the asymptotic behavior which is characterized by Stephan-Boltzmann limit would be satisfied.
