摘要：

Contact angles of water drops on a quartz optical glass plate were measured by the sessile-drop method. Before the measurements the heated plate (ca. 100 degree C) was dipped for a moment in an organic liquid (methanol, propanol, nitrobenzene, ethylene glycol, cyclohexanone, formamide, diacetone alcohol). The measured contact angles ranged from 14 to 30 degrees. Various models of interfaces in quartz/organic liquid-water drop-air system are discussed. The best agreement for measured and calculated contact angles is achieved when a mixed organic liquid-water film around the water drop and a spreading film of the organic liquid under the water drop is taken into account.
