摘　　要：It has been reported for over two decades that a fixed amount of non-freezable water’ exists in each species of biomacromolecule, even when taken well below the ice homonucleation temperature of about 232 K, as demonstrated by a variety of measurements. For instance, the amount of non-freezable water, R_nf, in lysozyme measured by various techniques is about 0.33±0.03 g（water）/g（protein）. It is usually believed that this fraction of water is hydrogen-bound to the macromolecule, maintaining tits
