| 摘 要： | 在对已有土壤粘附机理进行综合分析的基础上，从结构化学和量子力学的统计效应出发，对参与粘附的各种因素———土壤表面性质、触土部件表面特性、土壤水中各种离子的性质进行了全面分析，从化学吸附角度，提出了以化学吸附为主的土壤粘附机理。该模型认为土壤与触土部件金属材料表面的粘附力是由土壤与金属表面间的化学吸附力（包括物理吸附力）、土壤水在金属与土壤之间形成的化学吸附力（宏观上表现为毛细管力）和水的粘滞阻力三部分组成

| Abstract: | This paper analyzed the soil adhesion mechanism of chemical adsorption. Through study on the surface properties of soil and parts touching soil, soil water and various ion in soil water, an adhesion theory which indicates that chemical adsorption constitutes a main part was put forward. This model indicates that soil adhesion to metal surface touching soil consists of three parts, they are chemical adsorption force(including physical adsorption)between soil and metal surface, chemical adsorption force between metal and soil formed by soil water (macroscopically called capillary force) , and water viscous force. |
