将现代吴、闽方言的阳声/入声韵与中古音进行历时比较，分析现代吴、闽方言阳声/入声韵与中古非阳声/非入声韵的衍化问题。现代汉语阳声韵与中古非阳声韵的衍化主要有三种类型:其一，部分中古阳声韵在现代吴、闽方言中读作阴声韵；其二，部分中古阴声韵在现代吴、闽方言中读作阳声韵；其三，部分中古阴声韵在现代吴、闽方言中读作鼻化韵。现代汉语入声韵与中古非入声韵的衍化主要有两种典型情况:入声舒化和舒声促变。

The Evolvement of Yang Rhyme/Entering-tone Rhyme and Mediaeval Non-yang Rhyme/Non- entering-tone Rhyme in Modern Wu and Min Dialects

This paper has made a diachronic comparison between the characters of yang rhyme/entering-tone rhyme and the Mediaeval phonetics in modern Wu and Min dialects, and comprehensively analyzed the evolution of yang rhyme/ entering-tone rhyme and middle ancient non-yang rhyme/non-entering tone rhyme in modern Wu and Min dialects. The derivation of yang rhyme and mediaeval non-yang rhyme in the modern dialect can be divided into three circumstances. Firstly, the part of the mediaeval yang rhyme is pronounced as “yin rhyme” in the modern dialect; secondly, the part of the Mediaeval yin rhyme is pronounced as “yang rhyme” in the modern dialect; thirdly, the part of the Mediaeval yin rhyme is pronounced as “nose rhyme” in the modern dialect. The derivation of entering tone and Mediaeval non-entering tone in modern dialect can be mainly divided into two circumstances, including “disappearance of glottal coda in entering tone” and “an abrupt change of the level tone”
