摘　　要：目的建立弱拓扑分子格的初步理论。方法运用一一对应的思想和范畴论方法研究弱余拓扑的确定和弱拓扑分子格的范畴性质。结果证明了可以用弱闭包算子确定弱余拓扑,WTML(即弱拓扑分子格与保并连续映射的范畴)和TML(即拓扑分子格与保并连续映射的范畴)都是CL(即完备格与保并映射的范畴)上的拓扑范畴。结论扩展了拓扑分子格理论。Aim To build the theorem of weak topological molecular lattice,and discuss its properties.Methods The relation between weak closure operator and weak cotopology is studied with the help of bijection,by theorem of category,weak topological molecular lattice is discussed.Results Weak cotopology can be described by weak closure operator;and proved that both WTML（the category of weak topological molecular lattices and continuous mappings） and TML（the category of topological molecular lattices and continuous mappings） are topological categories on CL（the category of complete lattices and join-preserving mappings）.Conclusion The theorem of closure space in general topology is improved and supplemented.
