我们回顾了最近对过冷和玻璃水的研究，重点关注其复杂行为的可能起源。我们强调水-水相互作用的强方向性以及局部能量、局部熵和局部密度之间的竞争所发挥的核心作用。在这种情况下，我们讨论多晶现象（即存在不止一种无序固态），强调制备方案的作用和不同无序冰之间的转化。最后，我们提出了关于将多晶现象与无人区中可能发生的液-液转变联系起来的可能性的持续争论，在温度-压力窗口中，均质成核阻碍了对亚稳态液体形式水的研究。
We review the recent research on supercooled and glassy water, focusing on the possible origins of its complex behavior. We stress the central role played by the strong directionality of the water-water interaction and by the competition between local energy, local entropy, and local density. In this context we discuss the phenomenon of polyamorphism (i.e., the existence of more than one disordered solid state), emphasizing both the role of the preparation protocols and the transformation between the different disordered ices. Finally, we present the ongoing debate on the possibility of linking polyamorphism with a liquid-liquid transition that could take place in the no-man's land, the temperature-pressure window in which homogeneous nucleation prevents the investigation of water in its metastable liquid form.
