Abstract：
In this paper, we presented a nuclear density empicical formula of the nucleus, where we have established the connection between the nuclear density and the mean binding energy in nucleus. By using the formula, we can get the nuclear density for various nuclei with A≥12. By means of the nuclear density model, we calculate the nuclear effect function R^A1/A2(x,Q²). The calculated results are in good agreement with NMC experimental data.
