摘　　要：上下文无关语法(简称CFG)在自然语言的句法自动分析中已经得到广泛的应用。本文使用CFG来分析和描写汉字的结构,以部件作为汉字结构的枢纽,把汉字部件的11种结构方式看成CFG中的非终极符号,把末级部件看成CFG中的终极符号,使用树形图及其等价的括号表达式成功地对汉字的结构进行了形式描述。The context free grammar （CFG） was applied broadly in the automatic syntactic parsing of natural language processing. We use CFG to describe and analyze Chinese character structure. in the description and analysis of Chinese character, we regard the component of Chinese character as kernel pivot of Chinese character structure, then we take 11 construction patterns of Chinese character as non-terminal symbols of CFG, and we take the primitive components of Chinese character as terminal symbols of CFG. The structure of Chinese character is represented by the tree graph or its equivalent bracket formula.
