Association Line

联接线

A term used in non-linear phonology for a line drawn between units on different levels. The notion has been especially developed as a means of linking tiers in autosegmental phonology. From a phonetic viewpoint, these lines represent temporal simultaneity, indicating the relationship in time between the features represented at each tier, such as tones and vowels.

非线性音系学术语，指不同层面上的单位之间画的连线。这个概念的提出特别是为自主音段音系学提供一个连接不同音层的手段。从语音学的观点讲，联接线代表时间上的同时性，表明两个音层（如声调层和元音层）各自表示的特征之间时间上的联系。
