20世纪70年代认知革命后，隐喻意义发生机制研究取得了丰硕成果，但现有隐喻解释理论缺少与语用因素的界面探究，隐喻意义发生的具体机制无法得到解释。作为关联—语用视域下的新发展，临场性概念阐明了隐喻理解和解释过程中意义建构的关键心理机制，对认知隐喻理论的完善具有重要意义。本研究聚焦于关联理论导向下的隐喻阐释，强调临场性概念在隐喻理解中的核心作用，旨在丰富认知隐喻研究的理论框架，推进当代隐喻研究的深入发展。

Since the cognitive revolution in the 1970s, metaphor research has made fruitful achievements. However, the existing theories of metaphor interpretation lack interface exploration with pragmatic factors, and cannot effectively explain how the meaning of a metaphor is generated. Ad hoc concept, as an innovative development in the relevancepragmatic perspective, elaborates the core mechanism of meaning construction in the interpretation and comprehension of metaphor. This is of vital importance to the development of cognitive metaphor theories. On the basis of teasing out the progress of metaphor explanation and understanding oriented by Relevance Theory, this study highlights the central role of ad hoc concepts in metaphor comprehension, so as to enrich the theoretical framework of cognitive metaphor research and promote the development of contemporary metaphor pursuit.
