Abstract Using the Dyson–Schwinger equation and perturbation theory, we define the quark condensate with the quark current mass at finite temperature, and compare the quark condensate at finite temperature for the quark current mass m=0 and m≠0, respectively. The results show that the two-quark condensates have significantly different behaviors from the quark condensate in the chiral limit, and the quark current mass has a very important influence over the solution of the non-perturbative term.
