the case grammar

This paper presents an English generation system based on the case grammar representation of Japanese which is used in a Japanese-Chinese machine translation system developed by the paper′s authors.

本文在已开发的一个具有一定规模的基于转换翻译的日汉机器翻译系统的基础上，为了检验该系统的日语分析结果的表达能力，设计一个基于日语格语法表示的英语生成系统。

As a special case (implicit in yacc, rather than stated in the grammar), a 0 token indicates that there are no more tokens, and ends parsing.

作为一种特殊情况(在yacc中是隐式的，没有在语法中声明)，0标记表示不再有任何标记，解析结束。

In this case, the grammar has condensed two versions of a command (with and without Numbers) into one version that works both ways.

在这里，文法将两种版本的命令(带数字和不带数字)压缩成了能以两种方式工作的单个版本。
