Fairly important covers have point - countable bases, weakly bases, k - networks, sequence - neighbourhood networks and so on. fairly important mappings have quotient s - mappings, closed s - mappings, open mappings, open - and - closed mappings, com - pact - and - open mappings, perfect mappings, countable bi - quotient mappings, compact mappings
比較重要的覆蓋有點可數基，弱基， k網，序列鄰域網；比較重要的映射有商s映射，閉s映射，開映射，開閉映射，緊開映射，完備映射，可數雙商映射，緊映射。 -
This paper applied the character that linear subjective isometries preserve the geometric rank of a operator to characterize the onto isometries between compact operators space in weakly closed modules of nest algebras, and obtained the expressions of the isomtries
摘要利用運算元的幾何秩在線性等距映射下不變的性質研究了套代數弱閉模中緊運算元空間的線性等距離映射，最後得到其空間實現形式。
