英汉例句

• since a lexical analyzer is actually nothing more than a parser optimized to process data into token streams, spirit treats both parts of the process virtually identically.

  由于词法分析器实际上只是优化，加工成令牌流数据分析器多，精神对待这一进程的两个部分几乎相同。

• being a special compile tool, the source program of lex is simple. the compiled lexical analyzer constructed by lex has high efficiency.

  作为一种专用的编译工具，lex的源程序简单，编译后生成的词法分析程序效率高。

• flex, a lexical analyzer generator

  这是一个词汇分析器生成器

• perform lexical analysis program called lexical analyzer or scanner (scanner).

  执行词法分析的程序称为词法分析程序或扫描程序（scanner）。

• for instance, a simple lexical analyzer might count the words in its input.

  例如，一个简单的词汇分析器可能会为输入的单词进行计数。

• there is considerable leeway in deciding whether to recognize structures using the lexical analyzer or grammar rules. for example, the rules.

  选择词法分析器还是语法分析器，其差别是值得考虑的。比如，规则。

• corresponding tokens are created through lexical analyzer that is produced by flex and the tokens are transferred to byacc.

  由编译软件flex生成的词法分析程序产生相应的单词，并将单词传给byacc程序；

• the former cases represent design errors; the latter cases can often be corrected by making the lexical analyzer more powerful, or by rewriting some of the grammar rules.

  前者会产生设计错误，后者一般能通过加强词法分析器来修复，或者重写其中一些语法规则。

• firstly constructing lexical analyzer of our system by using analysis strategy of finite state automaton (dfa).

  首先，本文采用确定有穷状态自动机（dfa）的分析策略构造了本系统的词法分析器；

• the lexical analyzer using the lr parsing table unifies the construction method of lexical analyzer and syntax analyzer, simplifies the design and construction of compiler.

  使用lr分析表的词法分析器，统一了词法分析器和语法分析器的构造方法，简化了编译程序的设计和构造。
