土壤—固体表面粘附行为的热力学分析

依据界面热力学原理对土壤—固体表面粘附行为进行了分析。土壤粘附强度主要由毛细管作用力和界面水膜粘滞力构成,固体表面性质对其产生影响。本文还讨论了土壤动物体表特征,其体表憎水性、体表液的低粘滞性和亚宏观到微观层次上的非光滑结构是重要的表面特征。

Thermodynamic Analyses of Behaviour of Soil-Solid Surface Adhesion

Behaviour of soil-solid adhesion is analyzed on the principle of thermodynamics. The soil adhesive strength is mainly composed of capillary pressure and viscous resistance of the water film, which are affected by the nature of solid surface. The features of the cuticle of soil animals are discussed. Unsmoothed structure in all sizes from sub-micro to microscope and hydrophobicity of their cuticle and small viscous resistance of the sacretion on their skin are important features. Characteristics of the adhesion between soil and some metal materials are also tested.
