当一滴液体放在固体表面上时，它可以保持为有限面积的液滴，或者它可以在表面上无限地扩散。铺展的条件是形成单位面积的固液界面所获得的能量应超过形成单位面积的液-气表面所需的能量;或者，如果ysA为固-气界面能，~ SL为固-液界面能，yu为液-气界面能，则铺展：
When a drop of liquid is placed on a solid surface it may remain as a drop of finite area, or it may spread indefinitely over the surface. The condition for spreading is that the energy gained in forming unit area of the solid-liquid interface should exceed that required to form unit area of the liquid-air surface; or if ysA is the solid-air interfacial energy,~ SL is that of the solid-liquid interface, and yu is that of the liquid-air interface, then for spreading:
