The nuclear effects in the neutrino-nucleus charged-current inelastic scattering process is studied by analyzing the CCFR and NuTeV data. The structure functions F-2(xQ(2)) and xF(3)(x,Q(2)) as well as differential cross sections are calculated by using CTEQ parton distribution functions and the EKRS and HKN nuclear parton distribution functions, and these are compared with the CCFR and NuTeV data. It is found that the corrections of the nuclear effect to the differential cross section for the charged-current antineutrino scattering on the nucleus are negligible, the EMC effect exists in the neutrino structure function F-2(x,Q(2)) in the large x region, the shadowing and anti-shadowing effect occur in the distribution functions of valence quarks in the small and medium x region, respectively. It is also found that shadowing effects on F-2(x,Q(2)) in the small x region in the neutrino-nucleus and the charged-lepton-nucleus deep inelastic scattering processes are different. It is clear that the neutrino-nucleus deep inelastic scattering data should further be employed in restricting the nuclear parton distributions.
