摘要:
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.
