粗糙度，定义为材料表面的不均匀性，在确定工程部件或自然物体如何与其他物体及其环境相互作用方面起着重要作用。分形粗糙度的出现在自然和工程表面跨越一系列的长度尺度表明存在的共同的过程和机制的粗糙度的成核和演变。在这篇文章中，我们回顾了最近的进展，了解自然和工程表面的粗糙度和地形演变的起源及其与地下变形机制的联系。未来的研究方向，了解固体表面粗糙度的起源进行了讨论。
Roughness, defined as unevenness of material surfaces, plays an important role in determining how engineering components or natural objects interact with other bodies and their environment. The emergence of fractal roughness on natural and engineered surfaces across a range of length scales suggests the existence of common processes and mechanisms for nucleation and evolution of roughness. In this article, we review recent advances in understanding the origins of roughness and topography evolution on natural and engineered surfaces and their connection with subsurface deformation mechanisms. Directions for future research toward understanding the origins of roughness on solid surfaces are discussed.
