Spreading of a liquid over a dry smooth solid surface is analyzed in the case of complete wetting, negligible evaporation, and small Bond and Weber numbers. In the inner region, the approach of V. M. Starov et al. (Adv. Colloid Interface Sci. 50, 187 (1994)) is used and disjoining pressure effects are included. In the core region of the drop, both capillary and viscous effects are included to account for deviations from the constant-curvature profile near the inflexion point. The spreading laws for the drop radius, the apex height, and the dynamic contact angle are determined by matching the inner and outer solutions at the inflexion point. The results are compared with the model of Starov et al. (1994) and the experimental results of J. D. Chen (J. Colloid Interface Sci. 122, 60 (1988)). The model is not based on any fitting parameter.

在完全润湿、可忽略蒸发以及邦德数和韦伯数较小的情况下，对液体在干燥光滑固体表面的铺展进行了分析。在内区，采用了V. M. 斯塔罗夫等人（《胶体与界面科学进展》50, 187 (1994)）的方法，并考虑了分离压力效应。在液滴的核心区域，同时考虑了毛细效应和粘性效应，以解释在拐点附近与常曲率轮廓的偏差。通过在拐点处匹配内解和外解，确定了液滴半径、顶点高度和动态接触角的铺展规律。将结果与斯塔罗夫等人（1994）的模型以及J. D. 陈（《胶体与界面科学杂志》122, 60 (1988)）的实验结果进行了比较。该模型不基于任何拟合参数。版权所有1997年学术出版社。版权所有1997年学术出版社
