我回顾了晶格上高温QCD的最新研究结果。交错费米子和威尔逊型费米子的稳定进展允许对热QCD进行定量描述，其精度在许多情况下与零温度研究相当。手性夸克的模拟已经成熟，并且随着理论的发展，在临界区域的分析中引发了有趣的发展。根据新的数值和分析结果，讨论了手性跃迁的普适性类和轴对称的命运。输运系数和底氢光谱分析结果与重离子对撞实验和大型强子对撞实验结果比较一致。模型场理论、晶格模拟和高温系统展开有助于建立QCD高温相的连贯图像。（强耦合）夸克胶子等离子体被大量研究，并断言其作为一个鼓舞人心的理论实验室的作用。
I review recent results on QCD at high temperature on a lattice. Steady progress with staggered fermions and Wilson type fermions allow a quantitative description of hot QCD whose accuracy in many cases parallels that of zero temperature studies. Simulations with chiral quarks are coming of age,and togheter with theoretical developments trigger interesting developments in the analysis of the critical region. Issues related with the universality class of the chiral transition and the fate of the axial symmetry are discussed in the light of new numerical and analytical results. Transport coefficients and analysis of bottomonium spectra compare well with results of heavy ion collisions at RHIC and LHC. Model field theories, lattice simulations and high temperature systematic expansions help building a coherent picture of the high temperature phase of QCD. The (strongly coupled) Quark Gluon Plasma is heavily investigated, and asserts its role as an inspiring theoretical laboratory.
