Structural Description

（SD）结构描写

A term used in (especially classical) transformational grammar to refer to an analysis of a terminal string in terms of a labelled bracketing. In transformational analysis, the structural description identifies the input to a transformational rule: it specifies which phrase-markers are to be affected by the rule, i.e. which will ‘satisfy’ or ‘meet’ the conditions of the rule. The term structural analysis and structure index are also used.

（主要用于经典）转换语法术语，指用带标加括法对一个终端语符列的分析。在转换分析中，结构描写为转换规则找出一个输入：它指明哪一个短语标记将受规则作用的影响，即指明哪一个能“满足”或“符合”规则应用的条件。可替换术语是“结构分析”和“结构标引”。
