研究闭集格范畴（闭集格以及闭集格间保任意并、保余素元的映射组成的范畴）的定向极限，通过并半格的闭集格化这种方法在一定的假设下给出了闭集格范畴定向极限的具体构造。

英文摘要：

The direct limits in the category of closed-set lattices--the category of closed-set lattices and mappings which preserves arbitrary unions and nonzero co-prime elements is studied. By the way of closed-set-latticefies of join-semilattice, the structure of direct limits in the category of closed-set lattices is given on the certain condition.
