投射的递归性研究

On the Recursiveness of Projection

本文基于系统功能语法,着重考察投射的递归现象。研究发现,投射具有双重递归性:内在递归性和外在递归性。内在递归性是指当有且只有一个投射结构时投射成分和被投射成分之间的嵌入关系,它包括同级递归和异级递归。外在递归性是指当有两个或更多投射结构时上述嵌入关系在同一层次的重复或不同层次的嵌套,包括线性递归和嵌入递归。此外,本文还指出,当这两种递归性相互作用时,投射的递归性由外向内表现为外在递归性到内在递归性的过渡,外在递归性的终止恰是内在递归性的开始。

This paper investigates the recursiveness of projection based on Systemic Functional Grammar.It reveals that projection has dual recursiveness：intrinsic and extrinsic.The intrinsic recursivenss of projection refers to the case that if there is only one projection structure,the relationship of between the projecting and the projected elements is embedding;it can be classified into recursion at the same rank and that across different ranks.The extrinsic recursiveness of projection refers to the case that if there are two or more projection structures,the above-mentioned relationship of embedding is repeated either in a linear or an embedded way.Correspondingly,this type of recursiveness is divided into linear recursion and embedded recursion.In addition,this paper points out that when the two types of recursiveness interact with each other,the recursiveness of projection displays the transition from extrinsic to intrinsic recursiveness,the stop of the former being the start of the latter.
