平顶山方言古入声字演变中的方向和规律

The Orientation and Rules of Ancient Entering Tones of Pingdingshan Dialect in Evolution

平顶山方言古入声字中的韵母和声调正在向普通话靠拢,在这个过程中,人们选择的是"音类的类推替换",而非寻找"相似的音值"。不同的声母、韵母变异时间和特点都各不相同,韵母的变异明显先于声调,"调转韵必已转",外来音类和原有的音类在不同的层面构成叠置现象,变异的模式都属于普通话与方言两个不同的语音系统竞争之下的音类的突变。观察其演变的方向和规律对研究中原官话的演变具有重要意义。

The phonetic variation of ancient entering tones of Pingdingshan dialect is getting close to Mandarin Chinese.In this process,people choose sound class analogy substitute instead of seeking ＂similar sound value＂.Different Chinese initial consonants and vowels have different variation time and features,and the vowel variation is apparently prior to the consonant,that is,tone changes,and rhyme itself must follow.The superpose phenomenon formed in different levels of the loan sound class and the original sound class and all the variation patterns belong to the sound class change under the competition of two different phonetic systems： competition between Mandarin and dialects.Observing its evolution direction and regulation is of great significance to studying the Mandarin evolution of the Central Plains
