摘　　要：应用统计力学研究实际气体吸附，导出了吸附方程式的普遍形式，并给出气体分子在Ｋｅｅｓｏｍ势和Ｌ－Ｊ势作用下的具体形式．应用自动吸附仪测定微孔和中孔活性炭吸附Ｎ２的实验等温线，微孔炭的实验等温线和理论等温线吻合程度令人满意．In this paper, the adsorption is studied in the light of statistical mechanics, with the result that a universal isotherm equation of the adsorption has been found, and the practical isotherm equation for real gases is given when the interaction between gas molecules is depicted in terms of Keesom and the LennardJones potential. The experimental isotherms of the adsorption of medium and micro aperture charcoal are measured. It is seen that the agreement between theoretical and experimental isotherms of micro aperture charcoal is satisfred.
