求翻译：由于空气中O2分子体积比N2小，当经过压缩后的空气通过碳分子筛时，O2被碳分子筛吸附，N2由于体积较大不能被吸附而富集为纯净的氮气。是什么意思？

O2 molecular volume of air than n2 small, when after the compressed air through a carbon molecular sieve, o2 carbon molecular sieve adsorption, n2 larger can not be attracted to the enrichment of pure nitrogen.

Due to the air in 2 elements O N smaller than 2 small, when after compression of the air through carbon molecular sieves, O2 is carbon molecular sieve adsorbent, N 2 as a large adsorb and cannot be set to pure nitrogen.

Because in the air the O2 molecular volume is smaller than N2, after when immediately thereupon compression air through carbon molecular sieve, O2 by carbon molecular sieve adsorption, N2 because the volume cannot adsorb greatly concentrates for the pure nitrogen.

Due to the small volume ratio of N2 O2 molecules in the air, when the compressed air when carbon molecular sieve, O2 was the carbon molecular sieve adsorption N2 enrichment due to larger cannot be attracted to pure nitrogen.
