半格點-
Theorem 1. 3. 3 5 is an a - idempotent semiring, then 5 is a normal idem - potent semiring, if and only if s is a strong semilattice idempotent semiring of rectangular idempotent semirings
定理j設s是人一冪等半環，則s是正規冪等半環，當且僅當s是矩形冪等半環的強半格冪等半環 -
Finally, we show that is a semilattice of groups congru - ence if and only if ( na ) u is a seminormal subsemigroup on 5, where pna is a group congruence on the semilattice congruence class sa of 5
在這一章的最後文章緒出了半群s上的半格同燃so上的群同余pno的並i 』 upe成為s上的群的半格同余的充分必要條件為u （ na切oeyoey是s的半正規子半群 -
Aim in order to prove a semiring whose additive reduct is a semilattice and multiplicative reduct is a inverse semigroup to be a distributive lattice
摘要目的求證加法導出是半格、乘法導出是逆半群的半環成為分配格的充要條件。 -
Furthermore, in the second chapter semidirect product of 5 and te is discussed. we have the result that it is also clifford quasi - regular semigroup. besides semidirect product of s and te is semilattice of quasi - groups
進一步，論文又在第h章中討論了半群s和t的子半群te的半直積及其結構，得出了s和t 」的半直積也是clvj 。 -
In this dissertation, we characterize the congruences on a strong semilattice of semigroups by the congruences on those semigroups and prove that a sublattice of the direct product of the lattices of congruences on those semigroups is isomorphic to a sublattice of the lattice of congruences on the strong semilattice of semigroups
本文，我們主要利用一族半群上的同余刻劃其強半格上的同余，並討論這族半群的同余格的直積的子格與其強半格上的同餘子格的關系。 -
In the second chapter, we give the description of the least group congruence on a - regular semigroup s. in the third chapter, we describe the group congruences on a semigroup s and construct the semilattice of groups congruence on it
本文的第三章對一般半群上的群同余作了描述，並且對其群的半格同余進行了構造。在對群同余的描述中，事實上是把d -
Besides the study of general semigroup, the strong semilattice of inverse semigroups, bands, and normal bands are discussed. the main results are given in follow
除了對一般半群的研究，本文還對逆半群、帶、正規帶的強半格作了相關問題的討論。 -
Firstly, this paper introduces the new concepts of locally conditional upper semilattice ( in short, l - cusl ) and its ideal completion
本文首先引入局部條件並半格（簡記為l - cusl ）及其理想完備化等概念。 -
Consequently, the class pc of the p lus cupping computably enumerable degrees is not an ideal of ? the upper semilattice of the computably enumerable degrees
因此所有加杯可計算枚舉度組成的集合pc不是的理想，這里是所有可計算枚舉度構成的上半格。
