Provide a way to access the elements of an aggregate object sequentially without exposing its underlying representation. 提供一种方式访问聚合对象的元素,从而无需公开其底层表示法。
Based on these considerations, to begin with, a systematic assumption made concerning the underlying representation of the vowel inventory and segmental structure of the retroflex suffix is given. 基于上述考虑,论文首先对普通话元音系统和儿化后缀的音段结构进行了分析,提出底层元音系统有六个单元音的假设。
The survey shows that the emergence of OT is the inevitable development of generative phonology where the focus of interest has shifted from phonological rules and underlying representation onto constraints imposed on surface representation. 优选论的产生是在生成音系学发展过程中研究的重点从音系规则和底层表达转移到对作用于表层表达的制约条件的必然结果。
However, McNeill ( 1970 ) suggests that one-word utterances have the underlying representation of a full sentence but that only one element of this full sentence is realized in the surface structure. 以McNeill(1970)为代表的内在结构假设派认为儿章先天具有基本句法结构,独词语段有内在句法结构,但在表层结构只通过一个词来表达。
The specification provides an underlying model representation for BPMN graphics. 规范提供了BPMN图形的底层模型表示。
