义乌方言的入声可分为甲乙两类。甲类只有一读,离城区越远,喉塞尾保留越强,在地域上表现为不同的发展阶段。乙类有文白两读,白读舒化,各点在调值上的表现相当一致,但调类归并各不相同,遵循调值相似原则;文读的产生受权威吴语方言影响所致,类似于历史上杭州话入声由舒变促的过程。甲类与乙类的文读表现相同,造成区分上的混乱,但两者属不同历史层次,因此不能仅靠舒促来判断义乌方言乃至整个婺州片吴语入声的文白读。文章还从历时上讨论了甲乙两类白读入声的产生过程。 Yiwu dialect into the sound can be divided into two categories. Class A only first reading, the farther away from the city, the greater the retention of the throat plug tail, in the geographical performance of the different stages of development. Class B has both white and white reading and white reading, and the performance of each point is quite consistent on the transfer value adjustment, but the transfer of different types are different, following the principle of similar transfer value; the reading of texts is caused by the influence of the authoritative Wu dialect, Similar to the history of Hangzhou dialect by Shu change to promote the process. Class A and Class B have the same literary reading performance, causing confusion on the distinction. However, the two are of different historical levels and therefore can not be used solely to judge Yiwu dialect or even the entire Wuzhou Wu dialect. The article also discusses from the diachronic class A and B two kinds of white reading into the sound of the process.
