【摘要】 分形理论可以用于表征表面的粗糙程度．与其它常规的方法相比，例如均方根粗糙度，有许多长处．这一描述并不依赖于实验仪器的分辨率并且具有标度不变性．分形理论用于描述薄膜的表面或界面粗糙程度，可以提供许多有用的关于薄膜生长机理的线索．更多还原

【Abstract】 Multifractal theory is applied to the exposed characteristics of the surface roughness.Comparing to other methods, for example, normal rms roughness, it has many advangages.The description is not depended on the resolution of experiment.When multifractal theory is applied to the surface and interface roughness of thin films, it can provide some very useful clues to the growth mechanism of thin films.更多还原
