标题： The equation of state and surface tension of QCD in the first order phase transition region

摘要： 我们通过将手征和解禁闭序参量的参数化应用于功能QCD方法的计算，建立了QCD相结构的完整描述。 特别是在高化学势的第一阶相变区域，使用麦克斯韦构造的相变线以及来自自旋分解的共存边界线都被确定。 我们计算了包括数密度、能量密度、压强以及QCD稳定和不稳定相的自由能在内的热力学量。 此外，在应用QCD自由能不均匀性的经验描述后，我们得到了QCD第一阶相变的表面张力。 显示英文摘要

摘要： We build up a complete description of QCD phase structure by applying the parametrization of the chiral and deconfinement order parameters upon the calculations from functional QCD approaches. In particular in the first order phase transition region at high chemical potential, both the phase transition line using Maxwell construction and the coexistence boundary lines from the spinodal decompostion are determined. We compute the thermodynamic quantities including the number density, the energy density, the pressure and also the free energy for both stable and unstable phases of QCD. Additionally, after applying a phenomenological description of the inhomogeneity of the QCD free energy, we obtain the surface tension of the first order phase transition of QCD.
