凝聚态物质：一种物质，两种液体？

水和其他液体一样，可以冷却到冰点以下而不结晶。过冷水的物理性质是不寻常的：它的温度越低，它就越容易被压缩，而且它在冷却时膨胀的异常趋势也越明显。似乎这些特征还不够奇特，现在有证据表明两种不同形式的过冷水共存。一种纯物质的两种液态之间的相变以前从未被观察到。
Water, like any other liquid, can be cooled below its freezing point without crystallizing. The physical properties of supercooled water are unusual: the lower its temperature, the easier it is to compress, and the more pronounced its anomalous tendency to expand when cooled. As if these characteristics were not peculiar enough, there is now evidence for the coexistence of two different forms of supercooled water. A phase transition between two liquid forms of a pure substance has never been observed before.
