A view of contact angle hysteresis from the perspectives of the three-phase contact line and of the kinetics of contact line motion is given. Arguments are made that advancing and receding are discrete events that have different activation energies. That hysteresis can be quantified as an activation energy by the changes in interfacial area is argued. That this is an appropriate way of viewing hysteresis is demonstrated with examples.
本文从三相接触线和接触线运动动力学的角度给出了接触角滞后的观点。文中指出,前进角和后退角是具有不同活化能的离散事件。有人认为,滞后现象可以通过界面面积的变化量化为活化能。文中通过实例证明了这是看待滞后现象的一种恰当方式。
