江淮官話端系字讀塞擦音的語音變化

The Sound Change About Stops to Affricates on Duan-Xi in Lower Yangtze Mandarin

江淮官話端系字逢蟹開四、止開三韻母時讀塞擦音聲母，音變是：ti＞ti_z＞tsi_z＞ts，有的地方是：ti＞ti_z＞tci_z＞ts。端系聲母塞擦音變化的演變動因來自前高元音韻母-i高化後帶來的摩擦特性。元音擦化是高元音持續高化的結果之一，韻母擦化使前頭的聲母也附帶摩擦成分，造成了端系聲母由塞音t-、t^h-發展為塞擦音，有的地區發展為ts-、ts^h-，有的地區則是tc-、tc^h-。

The research is discussing about the sound change on words from Duan-Xi (端系) in the Lower Yangtze Mandarin. If the words from Duan-Xi with Xie-Kai-si (蟹開四) and Zhi-Kai-san (止開三) in middle Chinese, the words in some dialects today pronounce affricates. In other words, the alveolar stops (t- group) became affricates. Some places stops developed into dental affricates (ts- group)，and some were Palatal affricates (tc- group) . It resulted from the friction on high vowel -i. The change rule is : ti＞ti_z＞tsi_z＞ts or ti＞ti_z ＞ tci_z＞ts.
