中文摘要：

借助2种典型的处理夸克能量损失的方法，利用拟合深度非弹性散射实验数据得到的束缚核子中的部分子分布函数，分别计算了核Drell—Yan过程中的微分截面比随运动学变量x1的变化，并与费米实验室E866组的实验结果进行比较．比较结果一方面验证了核Drell—Yan过程中能量损失效应的存在，另一方面也说明了不同的处理夸克能量损表的方法对计算结果的影响．

英文摘要：

By means of two typical kinds of quark energy-loss expressions, the nucleon structure functions by fitting the deep inelastic scattering experimental data are used to calculate the variation of different cross section ratios to kinematic variable x1 in nuclear Drell-Yan process and contrast with the experimental results from Fermilab E866. The results from contrasting both show that there is an energy loss effect in nuclear Drell-Yan process and show that different models used to express quark energy-loss affect the calculated results.
