摘要：

The pion decay constant and mass are computed at low temperature within chiral perturbation theory to two loops. The effects of the breaking of Lorentz symmetry by the thermal equilibrium state are discussed. The validity of the Gell-Mann-Oakes-Renner relation at finite temperature is examined.
