Ever since its formulation, the Scherrer formula has been the workhorse for quantifying finite size effects in X-ray scattering. Various aspects of Scherrer-type grain-size analysis are discussed with regard to the characterization of thin films with grazing-incidence scattering methods utilizing area detectors. After a brief review of the basic features of Scherrer analysis, a description of resolution-limiting factors in grazing-incidence scattering geometry is provided. As an application, the CHESS D1 beamline is characterized for typical scattering modes covering length scales from the molecular scale to the nanoscale.
自其提出以来，谢乐公式一直是X射线散射中量化有限尺寸效应的主要工具。本文讨论了利用面探测器的掠入射散射方法对薄膜进行表征时，谢乐型晶粒尺寸分析的各个方面。在简要回顾了谢乐分析的基本特征之后，给出了掠入射散射几何中分辨率限制因素的描述。作为一个应用实例，对CHESS D1光束线在覆盖从分子尺度到纳米尺度的典型散射模式下进行了表征。
