我们研究了半无限层的行为，它最初被放置在两个方向无限的一半上，理想的晶体表面，然后由于单层粒子的随机运动而随时间演变。粒子动力学建模为存在远距离吸引粒子-粒子相互作用的川崎粒子-空位交换过程。根据解析可解的平均场型近似，我们计算了单层边缘的平均位移X(t)，并讨论了这种单层扩散（X(t) >），部分湿润（X(t) = 0）或从固体表面湿润（X(t) < 0）的条件。
We study the behavior of a semi-infinite monolayer, which is placed initially on a half of an infinite in both directions, ideal crystalline surface, and then evolves in time due to random motion of the monolayer particles. Particles dynamics is modeled as the Kawasaki particle-vacancy exchange process in the presence of long-range attractive particle-particle interactions. In terms of an analytically solvable mean-field-type approximation we calculate the mean displacement X(t) of the monolayer edge and discuss the conditions under which such a monolayer spreads (X(t) > 0), partially wets (X(t) = 0) or dewets from the solid surface (X(t) < 0).
