Body text
In this solution, X-ray reflectometry was applied to lubricant to analyze its film thickness. X-ray reflectometry is powerful technique to characterize very thin film. These data reveal the fact that the thickness of the lubricant is determined to be 0.7 nm.

Description
広沢作成（試料は松村石油 坂根氏）
Technique
X-ray reflectometry is performed by observing X-ray reflectivity from sample. X-ray reflectivity is affected by thickness of films, electron densities of films and substrate, and roughness at surface and interfaces. In this solution, thicknesses and electron densities of coated lubricant, and native oxide layer of Si substrate were obtained.
