  遮蔽因子
    In this paper, we analyse the spatial overlapping behavior of sea quarks of neighboring nucleons in nuclei in the small x region and give a relation between the nuclear shadowing factor R(x, Q~2, A) and the spatial overlapping factor △V_Λ(x)/V_Λ(x).
    本文分析了小x区原子核内邻近核子间海夸克空间重叠行为,给出了核遮蔽因子R(x,Q~2,A)与空间重叠程度因子△V_Λ(x)/V_Λ(x)的关系.

    In this paper,we prove analytically that the parton evolution model can provide a physical basis to the double x-rescaling model. Then we describe the nuclear shadowing and antishadowing effect in the small x region using the modified Alteralli-Parisi equation to improve the parton evolution model. The unified description of the EMC effect,the nuclear shadowing effect,and antishadowing effect is given without introducing the nuclear shadowing factor.
    用解析方法证明了部分子演化模型可为双重X重新标度模型提供物理基础,进而利用修正的Alteralli-Parisi方程描述小x区域的核遮蔽和反遮蔽效应,以改进部分子演化模型,使我们不必引入核遮蔽因子便可统一地描述EMC效应、核遮蔽和反遮蔽效应.最后,利用改进的部分子演化模型相当好地解释了核Drell-Yan过程的实验数据.
