2) new integrable type

4) decomposable generating class
可分解的生成类
1.
First I discussed the decomposable generating class and get that C is decomposable if and only if C =k (G ( C )) and G ( C )is decomposable.
本文主要研究了可分解层次模型的一些性质,首先研究的是可分解的生成类,得出了生成类C是可分解的当且仅当C =k (G ( C )),且G ( C )为可分解的结论,接下来利用可分解的生成类超图的超边分解,给出了生成类C的一种递归分解,这种分解使得C恰好分解为所有由生成元诱导的子生成类的直和,最后我根据C的上述分解给出了可分解层次模型的估计与检验的最简单形式。
