摘　　要：在文献[1]的基础上,继续利用语言X生成的星语言X*对部分码类进行了重新刻画,并借助对所定义的语言类的层次关系讨论,完成了对部分码类的层次关系讨论.对于C4,C8两个语言类,虽然讨论了其与Pri,T2语言类的层次关系,但仍然未能对其进行重新刻画,它们到底是由哪些语言组成的仍未得到解决.On the basis of Literaturel,the paper redescribes some codes by using the Star Language X~* derived from Language X and completes the discussion in the hierarchical relationship of some codes by the discussion of hierarchical relationship of defined language classes.In the case of Language Classes C_4 and C_8,although their hierarchical relationship with Pri and T_2 is discussed,what languages they are composed of remains unsolved.
