Abstract：
In consideration of the lowest order non-perturbative effect due to the quark condensate <qq>and gluon condensate on the quark propagator,we calculate QCD non-pertubative quark propagator under the chain approximation.Using the obtained non-perturbative quark propagator,we analyse the non-perturbative effect in the nucleon structure functions and show the non-trivial Q²-dependence in the nucleon structure functions.
