冷却表面结霜不仅会造成严重的破坏，而且会造成经济损失。因此，有必要从科学和技术上阐明冷却表面结霜的机理。此外，考虑到霜晶体的大小，需要进行纳米-微米尺度的研究。然而，这样的研究很少。因此，本研究的重点是在纳米-微米尺度领域测量霜晶体尺寸/结构和霜刮力的方法。在本研究中，提出了测量霜晶体尺寸/结构的方法，如直径，高度，霜晶体数量，相邻霜晶体之间的间隔，以及使用扫描探针显微镜（SPM）从冷却表面刮霜所需的力，并研究了这些方法的有效性。除了霜晶高度，这些测量的可行性进行了论证，霜的尺寸/结构和刮霜力的相关性的例子可以。
Frosting on a cooling surface causes serious damage as well as economic losses. Therefore, it is necessary to clarify the mechanism of frosting on a cooling surface both scientifically and technologically. In addition, taking the size of frost crystals into account requires nano-micro-scale investigation. However, there have been few such studies. Thus, the focus of the present study is methods of measuring frost crystal dimensions/structure and frost scraping force in nano-micro-scale fields. In the present study, methods by which to measure frost crystal dimensions/structure, such as diameter, height, number of frost crystals, and interval between adjoining frost crystals, as well as the force required to scrape frost from a cooling surface using a scanning probe microscope (SPM) are proposed, and the effectiveness of these methods is investigated. With the exception of the frost crystal height, the feasibility of these measurements was demonstrated, and examples of the correlation of frost dimensions/structure and frost scraping force could are presented.
