摘要：

The adsorption of nitrogen at 77 K on Y and ZSM-20 zeolites has been studied. The isotherms have been analyzed by use of the alpha-s method and the Dublinin-Radushkevich equation, and the microporous capacities, sizes of pores, and the external areas were evaluated. The mechanisms involved in the microporous filling of these solids, which have pores of uniform size and shape, are discussed.
