界面粘附中非光滑表面基本特性的研究

Basic Behaviour of Nonsmooth Surfaces in the Interface Adhesion

某些非光滑表面比光滑表面更能减小运动阻力,这是有悖于传统认识的最新发现。本文从界面粘附角度提出了光滑与非光滑表面的基本概念,分析了非光滑表面的种类及其特性,阐述了非光滑表面仿生研究及其应用的现代发展,并展望了非光滑表面仿生降阻的前景。

The motional resistance of some nonsmooth surfaces against fluid or semi-solid is less than that of the smooth surface. This new discovery is contrary to the conventional understanding. Smooth and nonsmooth surfaces in the adhesion are difined on the bases of the nonsmooth effects. The noasmooth surfaces are classified as geometrically, mathematically, mechanically, biologically nonsmooth sufaces and others, and their basic behaviour are analyzed. Especially, existing state and development of the bionic investigation into nonsmooth surfaces is introduced and prospect of bionic nonsmooth surfaces to reduce motional resistance is given.
