摘要
文章给出了对称拓扑分子格的直和概念,给出了拓扑分子格的直和的特征,证明了对称拓扑分子格的分离性Ti(i=-1,0,1,2)及可数性CⅠ,CⅡ是可和性质.
Concepts of direct sum of symmetric topological molecular lattices are given characterizations of direct sum of symmetric topological molecular lattices are given. It is proved that separation Ti （i=-1,0,1,2） and countability Ct ,C8 on symmetric topological molecular lattices are summable properties.
