提出了一种研究分子薄润滑膜松弛特性的新方法。厚度相关的扩散常数的测量通过监测的润滑剂膜厚度的时间衰减与良好控制的初始正弦厚度调制。润滑油膜厚度也可以通过在寻道模式下飞行滑块来调制，从而创建2D“mogul”图案。使用以前测得的扩散系数，这些巨头的弛豫进行了模拟，并与光学表面分析仪获得的实验弛豫图像进行比较。
This paper presents a novel method for studying the relaxation characteristics of a molecularly thin lubricant film. The thickness dependent diffusion constant is measured by monitoring the temporal decay of a lubricant film thickness with a well-controlled initial sinusoidal thickness modulation. The lubricant film thickness can also be modulated by flying a slider in seek mode, creating a 2D "mogul" pattern. Using the previously measured diffusion coefficients, the relaxation of these moguls is simulated and compared with the experimental relaxation images obtained with an Optical Surface Analyzer.
