Abstract：
By means of two typical sets of nuclear parton distribution functions, meanwhile taking account of the energy loss of the beam proton and the nuclear absorption of the charmonium states traversing the nuclear matter in the uniform framework of the Glauber model, a leading order phenomenological analysis is given in the color evaporation model of the E866 experimental data on J/ψ production differential cross section ratios R _Fe/Be( x _F). It is shown that the energy loss effect of beam proton on R _Fe/Be( x _F) is more important than the nuclear effects on parton distribution functions in the high Feynman variable x _Fregion. It is found that the J/ψ-nucleon inelastic cross section depends on the Feynman variable x _Fand increases linearly with x _Fin the region x _F>0.2.
