纯蒸汽大气中的运动接触线：classical physics唯一框架中的无奇性描述
Moving contact lines in a pure-vapor atmosphere: a singularity-free description in the sole framework of classical physics
摘要：
我们在这里表明，即使在没有“正规化”的微观效应（即在壁或分离的压力/前体膜的滑移），实际上没有奇异性出现的移动接触线所包围的纯蒸汽的液体考虑。即使衬底过热，也没有与蒸发相关的奇异性。我们认为，在润滑近似和一个经典的单侧模型，接触线前进/后退以恒定的速度，或不动，突然开始在（正式）裸露的固体表面与零或有限的接触角。
英文摘要：
We here show that, even in the absence of "regularizing" microscopic effects (viz. slip at the wall or the disjoining pressure/precursor films), no singularities in fact arise for a moving contact line surrounded by the pure vapor of the liquid considered. There are no evaporation-related singularities either even should the substrate be superheated. We consider, within the lubrication approximation and a classical one-sided model, a contact line advancing/receding at a constant velocity, or immobile, and starting abruptly at a (formally) bare solid surface with a zero or finite contact angle.
