摘要：
<正> In this letter we raise three special nearnesses called s-nearness, p-nearness and w-nearness. We obtain one to one correspondence between strongly paracompactification and s-nearness, paracompactification and p-nearness and weakly paracompactification and w-nearness respectively. Definition 1. Let （X） be a family of all the subsets of a topological space X and （X）, ∈ S（X） iff there exists an 0 = {Aa: a ∈ A}such that for each a ∈ A, X（A0∪Aa） , here A is an ordinal number and Definition 2. A nearness v on a T1-space X
