晕了，绞尽脑汁也想象不出来表面粗糙度与atomic level有何关系，不过atomic还有“极微的、微小的、微粒的”意思。

请问有没有哪位老师知道下面红色字体是什么意思？如果译成““从原子尺度上来看（矿物）表面粗糙度，（矿物表面上）存在（生长）台阶、扭折、空位等缺陷”，是否正确？

敬请赐教！谢谢！

In order to have a proper understanding of mineral surfaces, interfaces, and interfacial processes, we need to address a number of questions. These include: whether and how a pristine mineral surface (growth or cleavage) differs from a simple truncation of the bulk crystal structure in the arrangement of its atoms; the roughness of the surface down to atomic level and the presence of steps, kinks, vacancies and other defects; the chemical composition of the fresh surface, before and after interaction with air, aqueous fluid, organic species or microbe, and the nature of the actual interface between mineral and fluid, organic or microbe.
