Abstract：
In this paper, we analyse the spatially overlapping behaviour of the sea quarks of neighboring nucleons in nuclei in the small x region and give a relation between the nuclear shadowing factor R(x, Q², A) and the spatially overlapping factor ΔV_A(x)/V_A(x). By using this nuclear shadowing factor R(x, Q², A), we calculate the ratios of the average nuclear structure function and obtain ¹²C, ⁶³Cu and ¹¹⁶Sn, to the deuteron structure function and obtain nuclei which yield a better agreement between the calculated results and the experimental data.
