本文以热力学平衡实验为基础，结合溶质动力学实验，对中国河套灌区的４种供试土样，进行较系统的静态等温吸附实验，用静态均衡动力吸附实验和一维土柱动态吸附实验检验了离子吸附或解析量的变化；在分析比较国内外４种代表性吸附模型的基础上，提出了含有两种容量因子即土壤初始吸附量Ｓ＿８和最大吸附量Ｓ＿（ｍａｘ）的等温吸附模型（ＴＣＦＭ）：．具有明确的物理意义与严格的应用条件，有较高的数值模拟精度，可供土壤吸附研究参考。
Based on the thermodynamic equilibrium experiment and the solute kinetics experiment, four kinds of experimental soil samples from Hetao Irrigation District of China were systematically studied by static isothermal adsorption experiments. The static equilibrium dynamic adsorption experiment and one-dimensional dynamic adsorption experiment of soil column Based on the analysis of four representative adsorption models at home and abroad, the isothermal adsorption model containing two initial capacity S_8 and the maximum adsorption S max was proposed TCFM) :. Has a clear physical meaning and strict application conditions, a high numerical simulation accuracy for soil adsorption research reference.
