本文向读者展示了一种新的主题标引和主题索引的构思及有关计算机的应用。文章介绍了循环嵌会主题索引的主要标引技术─—以自然语序为基础的引用次序，用叙词、自由词及嵌套受控词，标引具有句法结构及词序固定的词串作索引款目揭示文献主要内容，采用“首先想到”原则确定检索入口词等。索引技术─—嵌套技术与循环轮排相结合，形成循环轮排款目与倒置检索入口词相结合的索引形式，以确保本索引特色的实现。

This paper introduces the main indexing technique of cyclic embedded theme index ──the quotation order based on natural language order, indexing word strings with syntactic structure and fixed word order by using thesaurus, free words and nested controlled words Section reveals the main contents of the literature, the use of “first thought” principle to determine the search entry words. Indexing Technology - The combination of nested technology and cyclic wheelbarrow forms an index form that combines cyclical wheelbarrow entries with inverted search entry words to ensure the implementation of this indexing feature.
