从液体表面的X射线反射率测量的定量解释，需要有条不紊的会计漫散射热毛细粗糙度的影响。在本文中，我们将讨论如何这需要仔细注意的实验分辨率的形状。这些考虑对于测量液体表面的固有结构因子是必不可少的，需要了解液体表面张力。最后，本文简要评述了从离镜面漫散射测量中提取表面张力的最灵敏方法。
Quantitative interpretation of X-ray reflectivity measurements from liquid surfaces requires methodical accounting of the effects of diffuse scattering from thermal capillary roughness. In this paper we discuss how this requires careful attention to the shape of the experimental resolution. These considerations, which are essential for measurement of the intrinsic structure factor of a liquid surface, require knowledge of the liquid surface tension. The paper closes with a brief comment on the most sensitive method for extraction of the surface tension from measurement of the off-specular diffuse scattering.
