摘　　要：语法隐喻(尤其是概念语法隐喻)是知识建构的重要语言资源,但鲜有研究聚焦于(概念)语法隐喻的知识建构过程。语义波理论关注知识积累的过程和途径,与概念语法隐喻具有同质性。本研究基于语义波理论,自建了一个小型物理学科语篇语料库,采用定性定量法,探究名词化概念语法隐喻语义波的类型及其在学科语篇中的知识建构过程。研究发现:(1)名词化概念语法隐喻语义波可分为语义凹波和语义平波;(2)语义凹波主要用来建构等级知识结构,语义平波主要用来建构水平知识结构;(3)语义凹波在物理学科语篇知识建构中的作用更为显著,且以语义凹波Ⅰ、Ⅱ和Ⅲ为主;(4)语义凹波的波峰大多由带限制语的过程事物化名词来构成。Grammatical metaphor,with a focus on ideational grammatical metaphors(IGMs),is an important linguistic resource for knowledge construction.However,few studies have explored the knowledge--constructing process of IGMs.The theory of semantic wave,which shares similarities with IGMs,focuses on the processes and approaches of knowledge accumulation.This study built a small corpus of physics disciplinary discourse and applied qualitative and quantitative methods to explore the types of semantic waves of IGMs and their contribution to the knowledge-constructing process in this domain.We found that (1)semantic waves of IGMs can be divided into semantic concave waves and semantic fatlines;(2)semantic concave waves are mainly used to construct hierarchical knowledge structures and semantic flatlines are mainly used to construct horizontal knowledge structures;(3)semantic concave waves play a more significant role in the construction of disciplinary discourse knowledge,with semantic concave waves I,II,and III being the most prominent;and (4)the peaks of semantic concave waves are primarily formed by nominalisations of processes with qualifiers.
