Abstract：
Taking into account perturbative QCD α_s order approximation, using double Q² rescaling model, the cross section ratios of Drell Yan process in p-A collision to p-D collision are calculated. Comparing these results with the ratios without QCD corrections, it shows the neclear effect functions R_QCD(x_A,Q²) are suppressed by different extent for different nucleus, in different ranges of x_A(T). Comparing with the E772 experiment data, R_QCD(x_A,Q²) are better fitted than R(x_A, Q²). It is shown that the QCD corrections are interesting in studing the nuclear effect of D-Y process. After taking into account of α_s order corrections, double Q²-rescaling model is still effective.
