本文运用密度函数理论（DFT）和杜比宁方程分别对活性炭纤维（ACF）的氮吸附等温线进行解析，经过两种解析结果的对比，验证了ACF上的多段充填机理，提出与各吸附段相对应的孔径范围，并讨论了各吸附段的吸附分压。在此基础上，比较了不同原料ACF的不同孔径结构对其多段吸附的决定作用。
In this paper, the nitrogen adsorption isotherms of Activated Carbon Fibers (ACF) were analyzed by density functional theory (DFT) and Dubinine equation respectively. After comparing the results of two analytical results, the multi-stage filling mechanism of ACF was verified. The corresponding pore size range, and discusses the adsorption partial pressure of each adsorption section. On this basis, the different aperture structures of different raw materials ACF were compared to determine their multi-stage adsorption.
