摘要
应用热力学关系,在Nicholson导出方程的基础上,假定间隙孔为两端开口的圆筒型,推导出从多孔固体在液氮温度吸附氮的等温线脱附分支计算其间隙孔径及吸附层液膜厚度的方程,并对用不同方法(经典法、BB法和本文方法)计算的结果进行了比较.
Using the principle of thermodynamics , this paper has derived the equations of calculating the mesopore radii and the thicknesses of adsorbed layer of porous solids from the desorption branch of a nitrogen sorption isotherm in the case of cylindrical pores at liquid nitrogen temperature . A comparison has been made between the equations presented in this paper and other various ones , also between the results calculated by them .
