摘要
对情报检索语言“标引耦合”这一普遍现象的原理进行了初步研究，并将其运用于情报检索语言词汇对应关系的研究及检索工具查全率与查准率的测定。
The heading coupling in information retrieval languages is a very frequently-occured phenomenon, but it has been seldom studied. The author has preliminarily studied the principle of the phenomenon and applied it in the studies of term correlation of information retrieval languages, and the measuring of recall ratio and precision ratio in retrieval tools.
