Structure Preservation

结构保持

A principle in lexical phonology which states that constraints on possible underlying segments in the inventory of a language, and constraints on autosegmental associations, hold thought the derivation during the lexical part of the phonology. These constraints are dropped during the post-lexical part of the phonology.

词汇音系学的一条原则；按此原则，对一种语言的音段中可能包含的底层音段的制约，对自主音段互相联接的制约，始终都在音系学的词汇部分的整个派生过程中起作用。这些制约在音系学的后词汇部分被放弃。
