英文摘要	In consideration of the lowest dimensional condensate contributions to the free quark propagator, we obtain the nonperturbative quark propagator with the nonvanishing vacuum average value for quark composite operator [\(q) over bar q\]. Using the [\(q) over bar q\]-corrected quark propagator and basing on the simple quark-parton model, we discuss the nonperturbative effect in the nucleon structure function. it is shown that the nonperturbative effect modifies the conventional quark-parton model formula of the nucleon structure function at finite Q(2) and suggests a nontrivial Q(2)-dependence in the Gottfried sum.
