标题： Nuclear Structure Functions from Constituent Quark Model

摘要： 我们使用了核子的组成夸克模型的概念，其中组成夸克具有其自身的内部结构，并将其应用于确定核结构函数比值。 发现描述实验数据需要包含对$x<0.01$的强阴影效应。 利用矢量介子主导模型和其他要素，这种效应在组成夸克模型的框架内进行了计算。 令人印象深刻的是，此处使用的组成夸克模型能够很好地解释从 A=4 到 A=204 的广泛原子质量数的数据。 显示英文摘要

摘要： We have used the notion of the constituent quark model of nucleon, where a constituent quark carries its own internal structure, and applied it to determine nuclear structure functions ratios. It is found that the description of experimental data require the inclusion of strong shadowing effect for $x<0.01$. Using the idea of vector meson dominance model and other ingredients this effect is calculated in the context of the constituent quark model. It is rather striking that the constituent quark model, used here, gives a good account of the data for a wide range of atomic mass number from A=4 to A=204.
