基于界面生长的动态尺度描述，在倒易空间中描述了与薄膜生长相关的多层阶梯表面结构的特征。结果表明，衍射光束的角强度分布通常包含中心峰值位置处的 6 函数和漫射强度，漫射强度是无数个不同宽度的特殊函数的总和。在同相衍射条件附近，6 强度是角度轮廓中的主要成分，它显示出作为生长时间的函数的稳定衰减
The characteristics of a multilayer stepped surface structure relevant to the growth of thin films has been described in the reciprocal space based on the dynamic scaling description of the interface growth. It is shown that the angular intensity distribution of a diffraction beam, in general, contains a 6 function at the central peak position and a diffuse intensity which is a sum of an infinite number of special functions with different widths. At the vicinity of the in-phase diffraction condition, the 6 intensity is the dominant component in the angular profile, which shows a steady decay as a function of the growth time
