复冰现象（1850）：

冰受压融化但撤压后再结冰。所以载重的细线在-10度左右可以穿过但不能切断冰块。冰川底部受压融化而形成河流之源。

机理【1，4】：

1)冰的熔化温度正比与H-O键能。

2)由于氧-氧间的电子对的库伦排斥和氢键(O:H-O)两段作用势的非对称性，受压时O:H键被压缩而H-O键被挤长；被挤长的H-O键变弱能量降低，所以冰的熔点降低。

3)当O:H断裂时,氧原子总是寻求新的近邻以稳定它的sp³轨道杂化结构。所以氢键有超强的自修复功能。

Unlike other unusual materials whose bonds contractunder compression, the O:H nonbond undergoes contraction and the H-O bondelongation towards O:H and H-O length symmetry in water and ice. The energydrop of the H-O bond dictates the melting point T_m depression ofice. Once the pressure is relieved, the O:H-O bond fully recovers its initialstate, resulting in Regelation.
