Abstract：
In this paper the meson structure functions are calculated by use of the method given in ref.[1]. It is obtained that W^π₁(x)~(1-x) for π-meson in the leading-order. Then an approximate expression of Resonance-Regge correction is introduced, and thus obtained nucleon and π-meson valence quark distribution functions are in good agreement with the data in the whole range of 0≤x≤1. Also, the possible influence of scaling violation to the number of passive quarks and to the effective bag-radius is suggested. Finally, it is pointed out that the sea-quark distribution functions can be estimated by using a similar Pomeron correction.
