摘要
在文献 (JournalofUESTofChina ,1992 ,2 1( 2 ) :188～ 190 )基础上 ,讨论了Fuzzy下推自动机按两种不同方式所接受的语言类的等价性 ,进而研究了Fuzzy下推自动机所产生的语言与Fuzzy上下文无关语言的等价关系 。
Based on the results(Journal of UEST of China,1992,21(2):188～190), the equivalence relation that a fuzzy language can be accepted by fuzzy pushdown automata in two different ways is disscussed. Moreover, the equivalence relation of languages derived from fuzzy pushdown automata and fuzzy context free languages is studied, and a method that a fuzzy context free grammer can be produced by fuzzy pushdown automata is provided.
