我们对靠近水的冰-液-气三相点的冰-气界面形成的冰的准液体层进行了计算机模拟。我们的研究表明，包围薄膜的两个不同的表面在小波长下表现为原子粗糙和独立的冰水和水蒸气界面。然而，对于长波长，两个表面耦合，大尺度平行波动被抑制，冰-蒸汽界面变得光滑。我们的研究结果可以帮助解释冰晶的复杂形态。
We perform computer simulations of the quasiliquid layer of ice formed at the ice-vapor interface close to the ice Ih-liquid-vapor triple point of water. Our study shows that the two distinct surfaces bounding the film behave at small wavelengths as atomically rough and independent ice-water and water-vapor interfaces. For long wavelengths, however, the two surfaces couple, large scale parallel fluctuations are inhibited, and the ice-vapor interface becomes smooth. Our results could help explain the complex morphology of ice crystallites.
