Abstract：
In this paper, an improved nuclear density model is presented. The formulas of nuclear effect parameters R _V ^A(x,Q ²) and R _S ^A(x,Q ²) for the valence quark distribution and sea quark distribution in nucleus are derived, in which the connection between the nuclear density and the mean binding energy in nucleus is used. In terms of this model, the experimental data of the averaged nucleon structure function ratio of DIS process in l-A are well explained.
