4) regular expression
正规式
1.

正规文法、ＮＦＡ、ＤＦＡ、状态转换图、正规式是形式语言理论的基础概念，也是编译原理词法分析理论中的重要概念和工具。
2.
To construct Lexical analysis,the NFA(Nondeterministic Finite Automata) equivalent to the regular expression should be constructed firstly according to the regular expression definition of words.
当构造词法分析器时,根据单词的正规式定义首先构造与正规式等价的NFA,之后用子集法将NFA转换成DFA,并用此DFA进行词法分析。
3.

介绍了Thompson算法的基本思想,提出一种利用算符优先关系表来实现Thompson算法的方法,以实现正规式到有穷自动机的转换。
5) formal rules
正式规则
1.
The logic of institutional compatibility is that formal rules must be based on informal rules and the agreement formed during peolpes long-term economic activity.
正式规则必须以非正式规则为本源,尊重人们在经济交往中达成的共识才能发挥效力,正式规则将对非正式规则起到进一步固化作用,这是正式规则与非正式规则相兼容的内在逻辑。
