我们最近发现了三种新的冰相，使已知的不同形态的冰的总数增加到15种。在这篇透视文章中，我们简要介绍了该领域以前的工作，并讨论了最近研究中出现的一些特别有趣的开放问题。这些包括（i）酸和碱掺杂剂在冰中实现氢有序过程的有效性，（ii）冰和低密度无定形冰的一些结晶相的量热数据的比较，（iii）实验冰XV结构和计算预测之间的不一致，（iv）一些氢有序/无序对的不完整性和（v）相图高压端和负压端的新边界。
Our recent discovery of three new phases of ice has increased the total number of known distinct polymorphs of ice to fifteen. In this Perspective article, we give a brief account of previous work in the field, and discuss some of the particularly interesting open questions that have emerged from recent studies. These include (i) the effectiveness of acid and base dopants to enable hydrogen-ordering processes in the ices, (ii) the comparison of the calorimetric data of some of the crystalline phases of ice and low-density amorphous ice, (iii) the disagreement between the experimental ice XV structure and computational predictions, (iv) the incompleteness of some of the hydrogen order/disorder pairs and (v) the new frontiers at the high and negative pressure ends of the phase diagram.
