摘要：

Pade approximants (PA's) are constructed from the perturbative coefficients of foe energy through O(g(5)) in hot QCD. Pade summation is shown to reduce the renormalization-scale dependence substantially even at a temperature (T) as low as 250 MeV. Also, PA's predict that the free energy does not deviate more than 10% from the Stefan-Boltzmann limit for T>250 MeV. [S0556-2821(98)04201-5].
