中文摘要：

复杂术语通常作为整体使用,具有词的特征,其中包含的其他术语或通用词的词汇地位下降为语素,即语素化。在该视角下,具体学科的复杂术语构词可描述为三层模型：首先学科基本概念由学科基元语素表征,然后由学科基元语素扩展构成固有语素组,最终由固有语素组扩展构成复杂术语。统计显示,在通信学科中超过80%的术语均包含学科基元语素,几乎所有术语均包含固有语素组。

英文摘要：

In Chinese,complex terms are usually used as one word,so other terms or general words that constitute the term can be seen as morphemes,so called morphemization. Under this view,complex term formation can be described as a three layer model： firstly,basic concepts of a subject can be described by a number of domain element morphemes;then,inherent morpheme groups are extended based on domain element morphemes; finally,complex terms are formed by using inherent morpheme groups. Statistics show that more than 80% terms in communication science contain domain element morphemes and almost all terms contain inherent morpheme groups.
