论鲁津条件

On the Lusin's conditions

提出几种变形的鲁津条件，并阐述它们之间的关系，利用这些结果，我们把经典的巴拿哈-查列茨基定理（[1]P．279）转化成容易证明的定理．

In this paper we put forward some variant Lusin's conditions and explained the relations between them. Using these results, we can transform the classical Banach-Zaliski theorem into the theorem which could be proved easily.
