根据ＰＯＬＡＮＹＩ位势理论，对运用某温度下的实验吸附等温线数据来推算其它温度下的吸附等温线的算法进行了探讨。分别利用ＰＲ，ＣＣＯＲ，ＭＣＳＰＴ等方程根据７８．８Ｋ温度下的吸附等温线来预测８９．９６Ｋ和７２．５Ｋ下的吸附等温线，并和实验数据相对比。结果证明ＭＣＳＰＴ、ＣＣＯＲ方程比ＰＲ方程更适于低温低压下吸附过程计算，理论计算结果与实验数据吻合较好，以ＭＣＳＰＴ方程最佳。
According to POLANYI geopotential theory, the algorithm of using the experimental adsorption isotherm data at a certain temperature to calculate the adsorption isotherms at other temperatures is discussed. The adsorption isotherms at 89.96K and 72.5K were predicted by the equations of PR, CCOR and MCSPT respectively based on the adsorption isotherms at 78.8K and compared with the experimental data. The results show that the MCSPT and CCOR equations are better than the PR equation for the calculation of the adsorption process under low temperature and low pressure. The theoretical calculation results are in good agreement with the experimental data, and the MCSPT equation is the best.
