Abstract：
In this paper using constituent-quark model of nucleon we have calculated nucleon structure functions of Oxygen nucleus and Uranium nucleus, and with which we have analysed O+U→μμ+X Drell-Yan processes. The evaluated cross sections are in good agreement with recent data of the NA38 Group. We have shown the total influence of all nuclear effects acting on these cross sections could change its magnitude even about 15%, thus the nuclear effects should not be neglected when discussing problems such as searching quark gluon plasma in the suppression phenomenon of J/ψ yields. Further more, phenomenological analysis shows that the K factor which characterizes contribution of perturbative QCD in this process decreases slowly as the lepton pair mass m increases, which is consistent with asymptotic freedom of QCD and agrees with previous results on this problem.
