Abstract：
We study the properties of QCD vacuum state in this paper. The
values of various local quark vacuum condensates, quark-gluon mixed
vacuum condensates, and the structure of non-local quark vacuum
condensate are predicted by the solution of Dyson-Schwinger
Equations in ``rainbow" approximation with three sets of different
parameters for effective gluon propagator. The light quark
virtuality is also obtained in a consistent way. Our all theoretical
results here are in good agreement with the empirical values used
widely in literature and many other theoretical calculations.
