This articletook Chinese senior high school students as subjects and found their acquisition order of relative clauses fully coincided with Ku-no’s Perceptual Difficulty Hypothesis but partly agreed with Keenan&Comire’s Noun Phrase Accessibility Hypothesis and Hamil-ton’s SO Hierarchal Hypothesis, which can provide implications and references for the English relative clauses’ learning andteaching.展开更多

In this paper,some characterizations of positive implicative BCK algebras are given by discussing the adjoint semigroups. Moreover,the semigroup differences between positive BCK algebras and implicative BCK algebras are discussed,and some semigroup characterizations of implicative BCK algebras are given.展开更多

With some special properties of 6-elements linguistic truth-valued first-order logic, we discussed the satisfiable problem of 6-elements linguistic truth-valued first-order logic and proposed a resolution method of 6-elements linguistic truth-valued firstorder logic. Then the resolution algorithm is presented and an example illustrates the effectiveness of the proposed method.展开更多

In this paper,the relationship between lattice implication algebras and MV algebra was discussed,and then proved that both of the categorys of the two algebras are categorical equivalence. Finally,the infinitely distributivity in lattice implication algebras were proved.展开更多
