将拓扑空间的连通类和不连通类推广到双预拓扑空间中,并给出了双预拓扑空间不连通类的一些性质。讨论了当双预拓扑空间的一个不连通类A中含有二元集上的某些双预拓扑空间时彤的结构。
Connectednesses and disconnectednesses of topological spaces are extended to bi-pre-topological spaces. Some properties of disconnectednesses of bi-pre-topological spaces are given. Also, the structure of a disconnectedness- es of bi-pre-topological spaces which including two-element spaces is discussed.
