摘　　要：在对Internet环境下数据库群检索系统进行检索的过程中,检索效率很大程度上取决于检索策略的质量。为提高检索策略的正确性,除了对检索需求进行主题分析之外,还必须理解和掌握检索策略设计过程中的根本原理和法则。系统地分析了数据库群检索系统、检索策略和检索需求三者间的内在逻辑关系,建立了检索策略抽象结构,在此基础上,进一步揭示了检索策略屏蔽原理并对这一原理的深刻内涵和实际应用法则进行了深入探讨。In the course of information retrieval, search efficiency depends largely on the quality of the retrieval strategy. In order to obtain a strategy with better accuracy,a mere thematic analysis on the retrieval requirement is not sufficient. It is indispensable, as well, to understand and master the fundamental principle and law throughout the process of designing a retrieval strategy. The article made a systematic analysis on the inner logical relationship among the database-group retrieval system, the retrieval strategy and the searcher＇s requirements, and thus established the abstract structure of the retrieval strategy.Based on this, the authour reveals the mask law of the retrieval strategy. Furthermore, an in-depth discussion on the profound implication of the law and its application principle is also available in the article.
