2、 can help us analyse the results of high energy proton-nucleus scattering experiments and high energy nucleon-nucleon scattering experiments. An iorn nuclear parton distribution which we utilized in this paper is genera

3、ted from nutrino process by NuTeV experiment group,another is HKN04 iorn nuclear parton distributions arived from the global fits to charged lepton deep inelastic scattering data.By utilizing them seperately we obtained

4、the valence,light sea and strange sea distributions and compared the results.We found that there are enormous differences between the two iorn parton distributions while getting the valence ,light sea and strange sea dis

5、tributions.We also compared the ratio of structure functions D Fe F F R 2 2 / = and D Fe F F R 3 3 / =from the two iorn parton distributions,and got a clear idear for the difference between the NuteV parton distribution

6、s and the HKN parton distributions. Our caculating results implied that in the charged lepton-nucleus and the neutrino-nucleus deep inelastic scattering processes,the nuclear effects to parton distributions in nucleus ar
