Abstract: The weakly revertible and the weakly inverse of finite automata with quasi-(hk)-order memory with delay k or k+1 are researched in this paper.A sufficient and necessary condition is given that a given finite automata of quasi-(hk)-order memory is a weakly invertible with delay k or k+1.A weakly inverse of finite automata with quasi-(hk)-order memory with delay k or k+1 is easily made according to results above.

Key words: quasi memory, memory, finite automata, weakly invertible, weakly inverse

摘要: 主要研究拟(hk)阶存贮有限自动机的延迟k步与k+1步弱可逆性,以及它的弱逆,得到了拟(hk)阶存贮有限自动机的延迟k步与k+1步弱可逆的充分必要条件,并且通过所得结果可以比较简便地构造出延迟k步与k+1步弱可逆拟(hk)阶存贮有限自动机的延迟k步与k+1步弱逆。
