位语法（ПГ）是作者通过对现代俄语三位动词进行实验性研究而建立起来的一种旨在为自然语言处理服务的理论体系。全文共分两大部分：首先以非形式化的表达方式介绍ПГ理论的基本概念、推理法则和层次结构；据此，文章进一步阐明俄语动词性句子的语法分析、语义分析和语用分析的设计思想以及主要算法，并用形式化的描写手段构建符合足句条件的核心句的句法位谐配模式、语义位框架模式和语用位序列模式，紧随其后讨论模式分析与知识表示之间的关系，充分揭示语言系统装置在言语活动（理解、生成和转换）过程中的运行机制。
The bit grammar (ПГ) is a theoretical system aiming to serve natural language processing through the experimental study of the three verbs in modern Russian. The full text is divided into two parts: First of all, the basic concepts, reasoning rules and hierarchy of ПГ theory are introduced in a non-formal way. Based on this, the article further clarifies the grammatical analysis, semantic analysis and pragmatic analysis of Russian verb sentences Ideas and main algorithms, and constructs the syntactic pattern, the semantic frame pattern and the pragmatic sequence pattern of the core sentence conforming to the full sentence condition by means of formal description, and then discusses the relationship between pattern analysis and knowledge representation Relationship, fully reveal the language system device in the speech activity (understanding, generation and conversion) in the operation of the mechanism.
