摘要 对于Y上的任意非平凡等价关系E,讨论了由E确定的夹心半群TE(X,Y,θ)的同余格C(TE(X,Y,θ)),证明了当θ是单射时,C(TE(X,Y,θ))可分解为3个不相交的完全子格[C(δ),Cα(δ)],[C(E),Cα(E)]和[C(ω),Cα(ω)].在此基础上考察了TE(X,Y,θ)上的一个同余τ,并证明了当E为单等价关系时,τ是[C(E),Cα(E)]中的唯一原子. The congruence lattice C(TE(X,Y,θ)) on sandwich semigroups TE(X,Y,θ) determined by anynontrivial equivalence E on Y is discussed. It is proved that C( TE(X, Y,θ)) can be decomposed into three disjoint complete sublattices [ C(δ), Cα (δ) ], [ C(E), Cα (E) ] and [ C(ω), Cα (ω) ] when θ is injection. Based on above,a congruence τ on TE(X, Y,θ) is searched,and it is proved that τ is a unique atom in [ C(E), Cα(E) when E is simple equivalence.
