Abstract：
By using color dipole model, the ratios of the p-A Drell-Yan cross section per nucleon for an 800GeV proton beam incident on Fe and D targets are calculated in the target rest system. It is shown that our calculations can quite well fit the E772 data with considering the nuclear shadowing effect in p-A Drell-Yan process and without the energy loss effect in it.
