摘要
According to extensive study of the Dyson-Schwinger equations for a fully dressed quark propagator in the ＂rainbow＂ approximation with an effective gluon propagator, a parametrized fully dressed confining quark propagator is suggested in this paper. The parametrized quark propagator describes a confined quark propagation in hadron, and is analytic everywhere in complex p^2-plane and has no Lehmann representation. The vector and scalar self-energy functions [1 - Af（p^2）] and [Bf（p^2） - mf], dynamlcally running effective mass of quark Mf（p^2） and the structure of non-local quark vacuum condensates as well as local quark vacuum condensates are predicted by use of the parametrized quark propagator. The results axe compatible with other theoretical calculations,
