在Drell-Yan过程αs 修正的基础上 ,引入遮蔽因子分别计算了不同能量下 p -A、A -A碰撞的K因子 ,把考虑遮蔽因子的量和没有计入遮蔽因子的量做了对比。结果表明 ,加入遮蔽因子后在小x段K值明显抬高 ,能量的不同遮蔽因子对K影响的趋势不变
Abstract：Introduce nuclear shadowing factor in the α s order corrections to the Drell-Yan process as its base. We calculated the K factor's of the different energy in the p-A, A-A, collision, differently and contrast considering shadowing factor's effect with not considering shadowing factor's effect. Result indicate, values of K-factor in the small x has been obviously raised after the way it is added to the nuclear shadowing factor.
