求翻译：由于空气中O2分子体积比N2小，当被压缩后的空气通过碳分子筛时，O2被碳分子筛吸附，由于N2分子体积大，所以不能被吸附而富集为纯净的氮气。是什么意思？

Air o2 molecular volume than n2 small, when the compressed air through the carbon molecular sieve, o2 carbon molecular sieve adsorption, due to the large volume of n2 molecules, it can not be attracted to the enrichment of pure nitrogen.

Due to the air in 2 elements O N smaller than 2 small, when it is compressed air through carbon molecular sieve, O2 is carbon molecular sieve adsorbent N2 molecules, and the volume is so big that it cannot be absorbed and rich set of pure nitrogen.

Because in the air the O2 molecular volume is smaller than N2, when is compressed after the air through the carbon molecular sieve, O2 by carbon molecular sieve adsorption, because the N2 molecular volume is big, therefore cannot adsorb concentrates for the pure nitrogen.

Due to the small volume ratio of N2 O2 molecules in the air, when when it is compressed air through the carbon molecular sieve, O2 is carbon molecular sieve absorption, due to the bulky N2 molecules, so cannot be attracted and enrichment of pure nitrogen.
