中文摘要：

分析了吸附质分子在吸附剂表面运动的可能模式，在有些情况下，吸附质分子在垂直于吸附剂表面的振动对吸附等温线的影响不可忽略．在考虑了振动能的贡献下，应用巨正则分布对吸附相的热力学性质作了初步的计算与分析．得到了吸附相在高低温极限条件下所处的热力学状态和态函数熵，以及平衡态时吸附相粒子数的相对涨落和吸附相热容量的表达式．

英文摘要：

Possible modes of adsorbing molecules＇ movement on an adsorbent＇s surface are analyzed, and in some cases the influence of the adsorbing molecules＇ oscillations perpendicular to the adsorbent＇s surface on its adsorbing isotherm should not be ignored. Considering the contribution by the energy of oscillation, we preliminarily make analysis and calculation of the thermodynamical performances of adsorbing phase, using the distribution of macro regular matrix, thus obtaining the thermo-dynamical state and entropy in which the adsorbing phase is under the extremities of high and low temperatures, the relative fluctuation of number of the adsorbing phase＇s particles and an expression for thermo-volume of the adsorbing phase.
