摘　　要：通过引入一个用来描述核遮蔽与反遮蔽效应的海夸克和胶子的重组因子，结合ｘ重新标度模型，在保持核动量守恒的条件下，统一描述ＥＭＣ效应，核Ｄｒｅｌｌ－Ｙａｎ过程和Ｊ／ψ光生过程，获得满意的结果。A recombination factor is employed which can describe the nuclear shadowing and antishadowing effects in the small x region. Based on the consideration of the nuclear momentum conservation, a unified description of the EMC effect, nuclear Drell-Yan process and inelastic J / ψ production is given in terms of the x-rescaling model with recombination factor.
