摘要：

Chiral properties of Wilson fermions in full QCD with two degenerate flavors at finite temperature are investigated by numerical methods. We show that when the quark mass is properly defined, for a given g (gauge coupling constant) and K (hopping parameter), its value is almost independent of whether the system is in the high-temperature phase or in the low-temperature phase. The temperature dependence of hadronic screening masses is consistent with the physical picture that both U(1) and SU(2) chiral symmetries are recovered in the high-temperature phase.
