据美国 Physics Today1995年7月号报道,劳伦斯伯克利实验室的萨尔梅隆(M.Salmeron)和他的同事们发展了一种全新的极化力显微术,它是在原子力显微镜(AFM)基础上的一种改进,由此得到室温下水凝结和蒸发的显微图象。研究人员发现,湿度低于25%时,形成液态水的均匀分子层。而当湿度增大时,原长方形的形态中会出现多边形,其单元的形状具有的角度约为60°和120°,其取向明显取决于下面的云母衬底。这时出现晶体结构,因而等效于某种类型的冰。 According to the July, 1995, Physics Today Today report, M. Salmeron of Lawrence Berkeley Laboratory and his colleagues developed a completely new polarized microscopy that uses atomic force microscopy (AFM) An improvement based on this results in a microscopic image of water condensation and evaporation at room temperature. The researchers found that when the humidity is less than 25%, a uniform molecular layer of liquid water is formed. When the humidity increases, the polygons appear in the original rectangular shape, and the shapes of the cells have angles of about 60 ° and 120 °, the orientation of which depends significantly on the underlying mica substrate. The crystal structure appears then, which is equivalent to some type of ice.
