Ultimate Constituent

（UC）最终成分

A term used in structuralist grammatical analysis to refer to the irreducible elements which are the result of an immediate-constituent analysis. For example, in the sentence The girls stopped the bus, the ultimate constituents would be the+girl+s+stop+ed+the+bus.

结构主义的语法分析用来指用直接成分分析法得出的不可再分析的成分。例如，句子The girls stopped the bus“姑娘们拦住汽车”，最终成分是the（定冠词）+girl“姑娘”+s（复数）+stop“拦住”+ed（过去时）+the（定冠词）+bus“汽车”。
