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.
对液体表面X射线反射率测量进行定量解释需要系统地考虑热毛细管粗糙度引起的漫散射效应。在本文中，我们讨论了这如何需要仔细关注实验分辨率的形状。这些对于测量液体表面的本征结构因子至关重要的考虑因素，需要了解液体表面张力。本文最后简要评论了从非镜面漫散射测量中提取表面张力的最灵敏方法。
