这些作者通过实验研究了多尺度粗糙度对接触角测量的影响，并提出了将Wenzel和Cassie-Baxter方程与18025178定义的三维粗糙度参数相结合的模型。为此，开发了一种基于统计方法（bootstrap和相关系数）的通用方法，并将其应用于聚丙烯织构飞秒激光器（55个表面，烧蚀深度=5-45 pm，深度/直径=0.07-0.53）。根据Wenzel和Cassie-Baxter模型中平面表面接触角theta(0)与纹理表面theta之间的相关性，提出了一种混合模型，粗糙度参数为发达面S-dr，封闭丘陵区S-ha和封闭山谷区S-da。(C) 2014 Elsevier Ltd.版权所有。
These authors experimentally investigate the influence of multi-scale roughness on contact angle measurements, and they propose a model combining the Wenzel and Cassie-Baxter equations with the 3D roughness parameters defined by 18025178. To do this, a generic methodology based on a statistical method (bootstrap and correlation coefficient) is developed and applied to a polypropylene textured femtosecond laser (55 surfaces, ablation depths=5-45 pm and depth/diameter=0.07-0.53). A mixed model is proposed according to the correlations obtained between the contact angle of a plane surface, theta(0) , and a textured surface, theta, with the roughness parameters as the developed surface, S-dr, closed hills area, S-ha and the closed dales area, S-da, with regard to the models of Wenzel and Cassie-Baxter.
