本文引入和研究德摩根拓扑代数的可数公理、可分性和连通性，拓宽了原有的结果。
Countability axioms, separability and connectedness are introduced and investigated for a DE Morgan algebra of topology. Thus the scope of a DE Morgan algebra of topology is extended.
引入了N -可分效应代数的定义，证明了N -可分效应代数是区间效应代数且N -可分效应代数可嵌入到可分效应代数中。
We introduce the definition of N-divisible effect algebras, then we show that N-divisible effect algebras are interval effect algebras.
