Obligatory Contour Principle

强制曲拱原则

In some models of generative phonology, a principle which disallows adjacent identical elements in a representation. It was originally proposed for tone languages, where it excluded sequences of identical adjacent tones (e.g. a sequence of High–High–Low would simplify to High–Low).

生成音系学的某些模型中，指一个表征式中不允许有两个相同的邻接成分这一原则。这条原则最初是为声调语言提出的，它排斥相同邻接声调的序列（例如高—高—低序列必须简化为高—低）。
