本文通过测试65名大学生的双语工作记忆和二语水平，探讨了双语工作记忆的静态内在结构和动态变化过程，并得出如下结论：（1）双语工作记忆静态内在结构存在共享性与差异性。共享性体现在：无论存储容量还是加工速度，母语和二语工作记忆都共享了大部分认知资源；差异性体现在：母语工作记忆各成分均优于二语工作记忆；二语工作记忆各成分均直接影响二语水平，母语工作记忆仅存储容量直接作用于二语水平，并且母语工作记忆主要以二语工作记忆为中介间接影响二语水平；（2）随着二语水平的提高，双语工作记忆的动态变化过程为：二语加工速度上升，加工速度对二语水平的影响下降，存储容量的影响上升，直至存储容量的影响超过加工速度，成为影响二语水平的最主要成分。

By testing bilingual working memory and second language proficiency of 65 college students, this paper analyzes the static structures and dynamic changes of bilin- gual memory, and the following conclusions are obtained：（ 1 ） the static structure of bilingual working memory contains both shared features and distinctive features. Shared features are reflected in：for both storage and processing components,L1 and L2 working memory share most cognitive resources. Distinctive features are reflected in： all components of L1 working memory exceed those of L2 working memory; all components of L2 working memory affect L2 proficiency directly while only storage capacity of LI working memory affects L2 proficiency directly. L1 Working memory mainly indirectly affects L2 proficiency with L2 working memory as an intermediary. （2） With the development of L2 proficiency, bilingual working memory changes：L2 processing rate speeds up while the impact of processing rate on L2 proficiency decreases. Meanwhile, the impact of storage capacity on L2 proficiency increases and finally it surpasses the impact of processing rate and becomes the most important influencing factor on L2 proficiency.
