Additionally, DB2 requires that you follow a basic syntax rule in order to detect the potential application of a spatial predicate.

此外，DB 2要求遵从基本的语法规则，以检测潜在的对空间谓词的使用。

If all conditions are met, including the simple syntax rule, it is still not ensured that a spatial grid index is used to satisfy the query.

如果所有条件都符合，同时也符合简单的语法规则，那么还不能保证可以使用空间网格索引来满足查询。

A design model of NC code complier based on ANother Tool for Language Recognition (ANTLR) was presented, which adopted the Extended Backus Naur Form (EBNF) to define the NC program syntax rule.

采用了扩展的巴科斯范式(EBNF)定义NC程序语法规则，提出了一种基于语言识别工具(ANTLR)的NC代码编译器的设计模型。
