主　　题：quark current mass quark condensates QCD sum rule Schwinger-Dyson equation perturbation theory 

摘      要：Using the Schwinger Dyson equation and perturbation theory,we calculate the two-quark condensates forthe light quarks u,d,strange quark s and a heavy quark c with their current masses *** results show thatthe two-quark condensate will decrease when the quark mass increases,which hints the chiral symmetry may be restoredfor the heavy quarks.
