Interaction between laryngeal features in Asian languages

通过对台湾南岛语、越南方言、Chamic语、苗语、通古斯语、突厥语、Dunganese语、延边朝鲜语、蒙古语等语言的实地考察，描述了这些语言的声门特征。同时，对这些语言的旧文献进行了调查和研究。因此，语文学文献也观察和追溯了声调、音型、经度等语音特征之间的各种相互作用关系。

Glottal features were described by the field investigations to Taiwan Austronesian languages, Vietnamese dialects, Chamic languages, Miao language, Tungusic languages, Turkic languages, Dunganese, Yanbian Korean and Mongolian, etc. In the meantime, investigations and researches of old documents of these languages were carried out. As a result, various relationships of interaction among phonetic features such as tone, phonation types and longitude etc. were observed and traced by philological documents as well.
