从实验上定量地研究了宏观曲率对纯净水池上平行玻璃板间弯月面蒸发的影响。与毛细管长度相比，板与板之间的间隙较小，因此表面曲率随间隙的减小而增大。半月板没有加热，钢板的热弛豫时间估计很小。由实验封闭空间中蒸汽压的时间演化得到的蒸发率和蒸发量随着板间曲率的增加而增加。根据包括我们在内的现有数据的比较，很明显蒸发速率和通量可以由曲率来组织，而不是周长(接触线长度)。(C)2017爱思唯尔有限公司。保留所有权利。
The influence of macroscopic curvature on evaporation of the meniscus between parallel glass plates standing on purified water pool has been quantified experimentally. The gap distance between the plates was short compared to the capillary length, so the surface curvature increased with decrease of the gap distance. The meniscus was not heated and the thermal relaxation time of the plates estimated to be small. The evaporation rate and flux, obtained from time-evolution of vapor pressure in an experimental enclosure, could increase with increase of the curvature between the plates. Based on the comparison among the existing data including ours, it was clear the evaporation rate and flux could be organized by a curvature, not a perimeter (a contact-line length).
