冰的晶体相：探索冰的复杂科学

Researchers probe the surprisingly complicated science of ice CHANCES ARE THAT ALL your encounters with frozen wa- ter—while trudging through slushy winter streets, perhaps, or treating yourself to cool summer lemonades—have been confined to one structural form of ice, dubbed Ih, with the h referring to its crystal lattice’s hexagonal nature. But there is so much more to ice than that. For more than a century scientists have been striving to push ice into extreme conditions, creating progressively more exotic structures—they’ve made more than 20 crys- talline forms to date, in fact, none of which we are likely to experience in our lifetimes. …
