Yagasaki et al. [Phys. Rev. E 89, 020301 (2014)] present results from a molecular dynamics trajectory illustrating coarsening of ice, which they interpret as evidence of transient coexistence between two distinct supercooled phases of liquid water. We point out that neither two distinct liquids nor criticality are demonstrated in this simulation study. Instead, the illustrated trajectory is consistent with coarsening behaviors analyzed and predicted in earlier work by others.
长崎等人[《物理评论E》89, 020301 (2014)]展示了分子动力学轨迹的结果，该轨迹说明了冰的粗化现象，他们将其解释为液态水两个不同过冷相之间瞬态共存的证据。我们指出，在这项模拟研究中既没有证明存在两种不同的液体，也没有证明存在临界现象。相反，所示轨迹与其他人早期工作中分析和预测的粗化行为是一致的。
