液滴在固体表面上扩散的过程中，有一个初始阶段，其中几个因素可能是重要的，然后是重力和流体粘度是促进和阻碍扩散的主要因素的阶段，最后是液滴周围的分子间力取代重力成为引起扩散的主要因素的阶段。对后两个阶段进行了近似分析。结果与有关扩散速率的现有实验数据非常吻合。在预测最后阶段的实验扩散速率时，使用作用于液滴边缘附近有限区域的分子间力比使用作用于液滴边缘本身的线力要好。
During spreading of a liquid drop on a solid surface, there is an initial stage where several factors can be important, then a stage where gravity and fluid viscosity are the chief factors promoting and resisting spreading, and finally a stage where intermolecular forces at the drop's periphery replace gravity as the main factor causing spreading. Approximate analyses for the last two stages are developed. The results are in excellent agreement with available experimental data on spreading rates. The use of intermolecular forces acting throughout a finite region near the drop's edge is superior to the use of a line force acting at the edge itself in predicting experimental spreading rates for the last stage.
