吸附势的定义为吸附质在界面进行物理吸附时，每1mol吸附质的自由能变化。气相吸附时，Polanyi 提出的用A=RTln(P0/P) 定义吸附势很有名，此处，R，T，P0，P分别为气体常数，绝对温度吸附质的饱和蒸汽压，吸附平衡压。
本文采用吸附势理论恢复了荥巩煤田谷山井田煤层含气量变化史。
Based on adsorption potential theory, the variable history of gas content in Xinggong coalfield was resumed.
ZEC吸附势用于评估活性染料，而色彩去除效率用于量测单一和混合染料溶液。
The adsorption potential of ZEC was assessed for reactive dyes and the color removal efficiencies were measured in single and mixed dye solutions.
用朗格谬尔公式和吸附势公式对实验数据进行了拟合，发现这两个公式与实验数据之间均存在着明显的偏差。
Fitting the experimental data to the Langmuir equation and the adsorption potential equation, we found that those equations deviated considerably from the experimental data.
