讨论了从欧氏格点上SU（3）胶子热力学中提取输运系数所需的形式。这些可以从能量-动量张量的热关联函数的解析延拓得到。分析了这种方法的可行性。首次尝试在8/sup 3/x4晶格上进行了Monte Carlo模拟，研究了能量动量张量的热关联函数的行为.的结果进行了比较，在碰撞时间近似的传输系数的解析计算。
We discuss the formalism needed to extract transport coefficients from SU(3) gluon thermodynamics on Euclidean lattices. These can be obtained from analytic continuations of thermal correlation functions of the energy-momentum tensor. The feasibility of such a procedure is analyzed. A Monte Carlo simulation on an 8/sup 3/ x 4 lattice has been performed as a first attempt to study the behavior of thermal correlation functions of the energy-momentum tensor. The results are compared with analytic calculations of transport coefficients in the collision-time approximation.
