In this paper,using Hartree-Fock single particle wave Function From a density-dependent skyrme interaction,were-examine the idea of causing nuclear shadowing that sea quarks from neighbour nucleons in nucleus may have spatial overlapping and make evolution at low momentum.It is found that the critical values of x,xn at the occurence of nuclear shadowing show a shell effect. At the same time,taking the different X-rescaling parameter for Valence and sea quark momentum distribution in the nuclear structure function,we discuss the affection of antishadowing on nuclear structure function and calculate the ratios of average nuclear structuTe function for the nucleus C,Fe,Cu and Sn, and deuteron structure function.The result is compatiable with the experimental data.

本文利用密度相关Skyrme相互作用给出的Hartree-Fock单粒子波函数,重新考察了低动量端核内邻近核子间海夸克空间重叠和演化导致核遮蔽效应的思想,发现核遮蔽效应发生的临界值X_(?)可能存在一定的壳层效应。同时,本文采用对核子结构函数中的价夸克和海夸克的动量分布分别作不同的x重新标度的方法,探讨了反遮蔽效应对核结构函数的影响。并计算了~(12)C、~(56)Fe、~(63)Cu、和~(118)Sn的平均核结构函数与氘核结构函数之比值,结果与实验值符合得很好。

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). By using this nuclear shadowing factor R(x, Q~2, A),we calculate the ratios of the average nuclear structure functions of nuclei ~(12)C, ~(63)Cu and ~(116)Sn, to the deuteron structure function and obtais a better agreement between the calculated result and the experimental...
