摘要：

The dynamics of water molecules in the vicinity of a hydrophilic interface is modified as compared to that of bulk water. Recent experiments performed in porous silica show that water dynamics is well described by a stretched-exponential intermediate-scattering function. The behaviour of confined water is similar to that of supercooled water at lower (approximate to 30 K) temperature. This temperature shift can be understood within the percolation model of water, assuming that only three hydrogen bonds can be formed between interfacial water molecules instead of four in bulk water.
