摘　　要： 本文的目的是用可消幺半群的强半格和基本恰当半群建立一类恰当半群的结构.首先,引入了类型μ恰当半群,然后构造了一类代数,Y-积.证明了每个Y-积是类型μ恰当半群;反之,每个类型μ恰当半群同构于一个Y-积. In this paper, our aim is to use strong semilattices of cancellative monoids and fundamental adequate semigroups to establish a construction of a class of adequate semigroups. We first introduce the concept of type μ adequate semigroups. Then, we construct a special kind of algebra called Y-product. It is proved that every Y-product is a typeμ adequate semigroup, and every type μ adequate semigroup is isomorphic to a Y-product.
