Abstract Water’s properties are exceptional at low temperatures. Dielectric constant demonstrates ferroelectric-like behavior. We treat an idea to interpret the fundamental feature of water, 240 K singularity, through the Maxwell speed distribution of freely moving water molecules. We use the ion-molecular model recently proposed by us, in which water molecules make the translation-oscillator movement with rapid potential/kinetic energy transformation. The model provides direct access to the velocity distribution through the kinetic energy of free thermal motion.

关于水中 240 K 奇点的问题

摘要 水在低温下具有特殊的特性。介电常数表现出类似铁电的行为。我们通过自由运动的水分子的麦克斯韦速度分布来解释水的基本特征，即 240 K 奇点。我们使用我们最近提出的离子-分子模型，其中水分子以快速的势能/动能转换进行平移-振荡器运动。该模型通过自由热运动的动能提供对速度分布的直接访问。
