摘　　要：用·-幺半群和这类半群的双系构造了PCA分块Rees矩阵半群,这类半群是PA分块Rees矩阵半群的一种推广,并举例表明一个半群可以是PCA分块Rees矩阵半群,但不是PA分块Rees矩阵半群.PCA blocked Rees matrix semigroups are constructed by ·-monoids and bisystems of ·-monoids,the class of PCA blocked Rees matrix semigroups is a generalization of the class of PA blocked Rees matrix semigroups.An example is given to illustrate the existence of a semigroup which is a PCA blocked Rees matrix semigroup but not a PA blocked Rees matrix semigroup.
