文章在韵律音系学框架下对新天津话连读变调进行调查分析。研究发现,两字组连读变调出现新老派之分,并导致三字组连锁变调呈现简化趋势。天津话连读变调过程以韵律-句法结构同构性为基础,同时受韵律结构合法性要求的制约,通过韵律单位——韵律词——定义其变调辖域。出于同构性、韵律结构合法性和音系规则本身的共同作用,韵律单位会呈现递归性。 Under the framework of prosodic phonology, the article conducts an investigation and analysis of the dialectal tone of the new Tianjin dialect. The study found that the two-character continuous reading tone changes the old and new points, and led to a simplified trend of the three-character chain tone. Based on the same structure of rhythm-syntactic structure, Tianjin dialect readjusting process is constrained by the legal requirements of rhythm structure. Its rhythm unit-prosodic word-is defined as its transitive jurisdiction. Due to the commonality of isomorphism, the validity of prosodic structure and phonological rules themselves, the prosodic units will exhibit recursion.
