Abstract: The nuclear effect functions in lA DIS process RHe/D(x, Q2)， RLi/D(x, Q2)， RC/Li(x, Q2) and RCa/Li(x, Q2) are calculated on the basis of the nuclear density model by using nuclear densities obtained from an empirical formula or the experimental values of the electromagnetic mean of radius square 〈r2〉， respectively．It is shown that the nuclear effect functions obtained from the empirical formula are in good agreement with the NMC experimental data， and better than the later ones．The empirical formula of the nuclear density can be used to study the nuclear effect of nucleon structure functions reasonably.
