Abstract：
With the Fermi motion corretion including the nuclear binding effect,we show that the major features of the EMC effect can be explained by using the Q ²- or x-rescaling mechanism.The x- rescaling mechanism can fit the experimental data better than the Q ²- rescaling mechanism in the region of 0.2 2- or x- rescaling parameters for the valence and sea quark momentum distributions in the nucleon structure function.It shows that by using the extended x- rescaling mechanism one can obtain a better agreement with the experimental data in the small x region.
