基于方言及文献材料,本文旨在揭示并说明汉语方言中普遍存在的h-化音变。这种音变由语义虚泛主导,尤其多见于口语词第二或末尾音节。总体来看,h-化音变不靠语音条件,只在一定程度上钟意于送气声母。 Based on dialects and literature materials, this article aims to reveal and explain the u-sound changes that are common in Chinese dialects. This tone is dominated by semantic vagueness, most notably the second or last syllable of the colloquial word. Overall, h-change does not depend on voice conditions, only to a certain extent, the clock intended to send consonants.
