关于用函数形式确切地描述吸附等温线已有不少研究.沈中和等认为,难于找到适合各种形状吸附等温线的理想函数形式,建议采用线性插值.但线性插值显然会使计算结果带来额外偏差.Buchner等和Zingales等曾提出用函数平滑或拟合整个吸附等温线,但此法受所选函数形式的限制并存在拟合误差,无法如实描绘某些吸附等 There are a lot of studies about the exact description of the adsorption isotherm by the function form, Shen Zhonghe et al. Think that it is difficult to find the ideal function form suitable for all kinds of shape adsorption isotherms, and the linear interpolation is suggested. However, To extra margin.Buchner et al and Zingales et al have proposed using the function to smooth or fit the entire adsorption isotherm, but this method is limited by the selected function form and there is a fitting error, unable to accurately describe some of the adsorption
