中文摘要：

讨论了广义Witt代数V=L（dα;α∈Q）的子结构,找出了它的两个无限维的单特殊子代数,证明了单特殊子代数之间的同构关系,并给出了该李代数的超特殊子代数集和子半群集之间的一一对应.

英文摘要：

The substructures and properties of the generalized Witt algebra V = the two single special infinite dimensional subalgebras of it are found out ,the gle special subalgebras is proved,and the one-to-one relationship between the bras and the set of subsemigroups is given. L（dα;α∈Q） are discussed, isomorphism among the sinset of super special subalge-
