摘要：

The role of geometric surface features on the van der Waals and electric double-layer interactions of two parallel flat plates is studied. Equations are developed using the Hamaker metod for van der Waals forces, and Derjaguin's method for electric double-layer forces. The surface features are limited to spherical and conical asperities which include truncated asperities as well. The importance of asperities in surface interactions is assessed by using the interaction ratio, defined as the ratio of the interaction energy of a sysem with an asperity to that of the system without one. © 1990.
