论文摘要
我们考虑了抛物线体之间毛细血管颈和介于两者之间少量液体的平面之间的经典问题。在热力学平衡状态下，身体和液体层之间的接触面积具有圆形形状。但是，如果被迫沿切向方向缓慢移动，则由于接触角的滞后，形状将变化。我们讨论了在边界线中有关摩擦法的两个限制假设下的接触区域的形式。
We consider a classical problem of a capillary neck between a parabolic body and a plane with a small amount of liquid in between. In the state of thermodynamic equilibrium, the contact area between the bodies and the liquid layer has a circular shape. However, if the bodies are forced to slowly move in the tangential direction, the shape will change due to the hysteresis of the contact angle. We discuss the form of the contact area under two limiting assumptions about the friction law in the boundary line.
