Abstract：
Based upon the consideration of the Fermi motion correction and the nuclear binding effect, the EMC effect can be explained by introducing the Q²- and x-rescaling mechanisms. The experimental data, especially in the region 0.2 < x < 0.5, can be better reproduced by using the x-rescaling mechanism than using the Q²-rescaling mechanism. The problem of the nuclear momentum conservation in the EMC effect is further discussed. In order to make up the 4% nuclear momentum loss, the different Q²- or x-rescaling parameters for the momentum distributions of the valence and sea quarks in the nucleon structure function are chosen. The result shows that, by employing the extended x-rescaling mechanism, a better agreement between the theoretical result and the experimental data in the small x region can be obtained.
