中原官话??型复元音研究

Research on the Type Diphthong of ?? in Zhongyuan Mandarin

文章采用共时和历时相结合的方法研究中原官话??型复元音的产生过程、原因以及?的性质。从方言语音系统、音位功能和历史来源角度说明?的性质,再利用共振峰斜变化进一步验证;从历时角度分析新郑话??产生的过程,并通过与北京话比较揭示其产生原因。研究表明,新郑话??前一时间段的共振峰斜率变化大于后一时间段,?应为介音,非主元音;新郑话此类字声母时长大于北京话,受卷舌声母及其发音时间较长的影响,车遮韵卷舌声母字的介音在新郑话中由舌面音i变为舌尖卷舌音?,在北京话中消失。

Based on Xinzheng dialect,through both of the diachronic and synchronic perspectives,this paper aims to determine the nature of■and the evolution of■■in syllables.The type diphthong of■■is widely distributed in Zhengkai branch,Guanzhong branch and Fenhe branch of Zhongyuan Mandarin.Inherited Zhongyuan Yinyun,Such diphthongs come from open mouth syllables of Jia She,Shan She and Xian She in mediaeval times.The change of formant in the previous period is greater than the latter periods.The evidence shows that the nature of■is a glide,not a nuclei.Affected by the retroflex consonants and its pronunciation time,the medial is changed from the dorsal vowel to the retroflex vowel.
