山东方言鼻化韵的类型与政区、地理之关系

现代方言材料、历史文献、方言地理学和实验语音学的证据共同表明,北方地区鼻化韵有三种演变类型：始于an类音的,在随后的扩散过程中分化为两种类型：一是以韵尾-n为条件,一是以韵腹a类音为条件;第三种则始于aN类音。山东方言属于第一种类型。

On the Typology of Nasalization Rhymes in Shandong Dialect and Its Connections with the Political and Geographical Circumstances

Evidences provided by modern dialect materials,historical documents,dialect geography and experimental phonetics jointly attest to the fact that the nasalization rhymes in northern dialects have three types of evolution.The first two are all derived from the ＂an＂ class sounds,which come into being in the sound diffusion movement afterwards：one is conditioned upon the tail vowel ＂-n＂,and the other upon the essential vowel ＂a＂.The third type originates from the ＂aN＂ class sound.Shandong dialect belongs to the first type of the above discussed.
