首先得到了与g不可α-归结的广义文字的集合D*α(g)做成了∨-半群且也是一个序滤子;其次研究了由D*α(g)所确定的一个新的代数结构Df,Df做成一个格滤子,并研究了Df的一些相关性质;最后研究了由Df所确定的代数结构κ(D),得到了κ(D)构成滤子并研究了κ(D)的结构。
First, the generalized literals set D*α(g), which couldn't be a-resolved with a fixed generalized literal g, was a V -semigroup and an order filter. Second, a new algebraic structure D^f determined by D*α(g) was a lattice filter, and the properties of D^f were investigated. Finally, the algebraic structure K(D) was determined by D^f, the fact that K (D) was a filter was obtained and the structure of K(D) was studied.
