| 摘 要： | 编译程序的编制过程中,人们首先接触是语言,而上下文无关文法是作为程序设计语言重要的语法描述工具。因此,只有将语言用上下文无关文法表示才能使用现有的技术,从而用计算机自动实现。通过应用模块法将语言进行模块化划分,并在模块内实现杂凑,能够成功地、方便地实现语言到上下文无关文法的转换。

| Abstract: | People know the language at first when they program the compiler.A context-free grammar is a specification and an important tool for the structure of the programming language.The second,the computer can accomplish it automatically with the existing technologies.At last,the paper describes the modular procedure in programming,fulfils the knock-together in module,and realizes the transition from the language to a context-free grammar successively and effectively. |
