阐述一个基于合一算法的高效的通用型语法分析器系统的设计原理和方法.着重说明：一种基于功能文法的语法规则的表示形式；基于树的合一算法的原理及其分析；以及如何使系统既具有运行的高效性又具有调试的方便性的总体设计方案.A design scheme For a general purpose parser generator is presented.The principle of the system design is based on the Formalism of Lexicon Functional Grammar and a Tree UniFicational algorithm.To strengthen the Functionality of the system, the system is divided into two subsystems in this design: a testing environment and operational environment, both of which adopt similar but diFFerent control schemes, so that they can obtain diFFerent design goals at the same time keep their cooperation very well.福建省自然科学基
