Abstract

The temperature at which "clean" supercooled water freezes has been determined as a function of pressure up to 3 kilobars, using a differential thermal analysis technique on subdivided water samples. The supercooling limit of such samples, -38 degrees C at normal pressure, is lowered by initial increase of pressure, reaching a minimum value of -92 degrees C at 2.00 kilobars.

摘要

已经确定了“清洁”过冷态水在 3 千巴压力范围内的冰点随压力变化的函数关系,方法是对细分的水样使用差示热分析技术。在常压下,这些样品的过冷极限为-38°C,通过初始增压,过冷极限会降低,在 2.00 千巴时达到-92°C 的最小值。
