液体在固体表面上的扩散在日常生活、工业过程和生物现象中经常遇到。尽管这一过程经常发生，但人们对液体在固体表面上扩散的机制知之甚少（I）。在固-液-气接触区，液体运动类型的各种模型已经被假定和讨论过（2-9），特别是为了消除连续流体力学的无滑移条件所带来的困难。然而，正如一些实验观察所表明的那样（10-12），对初级膜的影响没有给予足够的注意，初级膜在液体主体之前扩散。一次成膜的机理尚不完全清楚。哈代（10）首先报道了这种薄膜的存在，他认为这种薄膜是由蒸气中的液体沉积而成的，后来的工作（11，12）提出，表面
The spreading of liquids on solid surfaces is frequently encountered in daily life, industrial processes, and biological phenomena. Despite the common occurrence of this process, little is known about the mechanism by which a liquid spreads over a solid surface (I). Various models for the type of motion exercised by the liquid at the solid-liquid-gas contact region have been postulated and discussed (2-9), especially in an effort to eliminate the difficulty posed by the no-slip condition of continuum hydrodynamics. Insufficient attention, however, has been given to the effect of the primary film, spreading ahead of the bulk of the liquid, as indicated by a few experimental observations (10-12). The mechanism of primary film formation is not yet entirely clear. While Hardy (10), who first reported the existence of such a film, believed that it was formed by deposition of liquid from the vapor, later work (11, 12) suggested that surface
