摘要该文将命题逻辑的定理证明转换为多项式方程的求解问题，从而提出了一种基于非子句的代数化方法。 - As a member of the team researching and developing the new generation of atc ( air traffic control ) system ( named mrd2k - jh ) for chinese air force , the author devotes his energies in the work of fdp ( flight data process ) . this thesis first introduces what is atc system and the present status of atc systems in china , then sets forth the design and structure of the new mrd2k atc system , based on the research and adjustment to the actual environment , essential technical points of fdp are presented in detail : the interface of traffic telegram and decoding algorithm : in this part , the application interface of eicon x . 25 card for mrd2k is introduced , and then the realization of a decoding algorithm based on context - free grammar is described in detail , which replaces the traditional method that decoding each telegram using a corresponding subprogram
本文基于我国新一代军航空中交通管制( airtrafficcontrol )系统mrd2k - jh的研制开发过程，首先介绍了空中交通管制系统的概况和现状，然后从建立空管自动化系统的角度阐述了mrd2k的详细设计和系统结构，接着结合作者参与的系统重要部分飞行数据处理( flightdataprocess )的工作，在进行了大量深入研究和与实际环境相切合的基础上，针对其中的诸多技术细节，提出了经实际验证富有效用的解决方案。 - First , the paper researches the format and semantic features of iso apt in detail , next , applies regular expression to describe the definition of apt ’ s tokens and uses context - free grammar to describe apt ’ s syntax rules , last , designs the intermediate code format which keeps on the source code semantic and designs a complete module to check lexical and syntax errors of nc code by using modern compiling techniques
在代码预处理技术方面,详细研究了标准数控代码语言的格式和语义并采用现代编译技术中的正则表达式和上下文无关文法分别描述了标准数控代码语言的记号定义和语法结构定义;设计了保持源代码语义的中间标准数控代码格式,在此基础上,设计并构建了数控代码的词法和语法检查模块。
