我们建立了固体薄片与液体亚相接触时曲率的尖点的存在。我们研究了两种浮片结构，其中固-气-液接触线分别为直线和圆。在前一种情况下，矩形薄板在其一侧被提起，而在后一种情况下，在浮动薄板下方注入气泡。我们证明，在这两种几何中，薄片曲率的导数是不连续的。我们证明了在这两种几何形状中，接触处的边界条件是相同的，即使接触线的形状和薄片中的应力分布非常不同。
We establish the existence of a cusp in the curvature of a solid sheet at its contact with a liquid subphase. We study two configurations in floating sheets where the solid–vapor–liquid contact line is a straight line and a circle, respectively. In the former case, a rectangular sheet is lifted at its one edge, whereas in the latter a gas bubble is injected beneath a floating sheet. We show that in both geometries the derivative of the sheet's curvature is discontinuous. We demonstrate that the boundary condition at the contact is identical in these two geometries, even though the shape of the contact line and the stress distribution in the sheet are very different.
