bottom up parsing

In this paper, through the concrete examples, the author introduces two kinds of parsing approaches: bottom-up parsing and top-down parsing.

通过具体的实例，介绍了两种基于短语结构语法的剖析方法——自底向上剖析和自顶向下剖析。

Adopting bottom-up parsing algorithms, the parse analyse the sequence of tokens and form the syntax tree of EP program.

语法分析采用自底向上分析方法，根据语言语法分析标记序列，构建程序的语法树。

LR analysis of expression grammar for the bottom-up parsing algorithm everyone operations for reference purposes only, attitude is everything.

LR分析法对表达式文法进行自底向上语法分析的算法个个作业仅供参考，态度决定一切。
