[求助] external area的测试与计算

在《co2 adssorption in single walled carbon nanotubes》这篇文献中提到:“when the total area is used, an cross sectional area is obtained, whereas the external area alone results in another value for the cross sectional areas ”.
google了external area, 《manual of symbols and terminology for physicochemical quantities and units》给了external surface一个定义:when a porous solid consists of discrete particles it is convennient to discribe the outer boundary of the particles as external surface.
文献中的total area指的是前面用N2 adsorption测得的结果,但是external area 是怎么得到的呢?
希望大家不吝赐教![ Last edited by nxl5096224 on 2011-11-23 at 21:35 ]
