英文摘要	The renormalization group invariant quack condensate <(mu)over cap> is determined both from the consistent equation for quark condensate in the chiral limit and from the Schwinger-Dyson (SD) equation improved by the intermediate range QCD force singular like delta(q) which is associated with the gluon condensate. The solutions of <(mu)over cap> in these two equations are consistent. We also obtain the critical strong coupling constant alpha(c) above which chiral symmetry breaks in these two approaches. The nonperturbative kernel of the SD equation makes alpha(c) smaller and <(mu)over cap> bigger. An intuitive picture of the condensation above alpha(c) is discussed. In addition, with the help of the Slavnov-Taylor-Ward (STW) identity we derive the equations for the nonperturbative quark propagator hom the SD equation in the presence of the intermediate range force and find that the intermediate-range force is also responsible for dynamical chiral symmetry breaking.
