摘要
本文讨论了原子核遮掩效应对EMC效应可能的贡献.根据众多的实验数据构造了一个能较好地描述遮掩效应的唯象关系,这一关系与通常人们表述遮掩效应的方法不同,是用通常结构函数的变量来表示的.
The paper the nuclear shadowing contributes possibly to the EMC effect is discusssed. We have constructed a better phenomenological formula to describe the shadowing effect from the many experiment data. It is different from the usual form, and we denote it to use the variables of the normal structure function.
