摘要
在部分子概念上提出了一种关于核子结构函数的统一理论描述。由此，包括小布约肯变量ｘ范围的遮蔽、反遮蔽，中等ｘ范围及大ｘ范围的ＥＭＣ效应的全部特征都可以给出解释。指出了深度非弹散射现象中部分子图象与传统核理论Ｎ一π图象的关联。理论计算结果与最近实验数据很好的符合。
A United theoretical description of the nuclear structure function is presented at parton level.From this,an explanation of all characteristics of the EMC effect in the small Biorken variable,x rogions including shadowing and antishadowing ,in medium x regions and in large x regions, is given. An relation between the parton picture and the conven-tional nucleal N-π picture is shown in deep inelastic scattering phenomena. Theoretical re-sults agree well with the recent experimental data.
