Abstract

The vitrification temperature (T(g)) of water is an elusive quantity because of the great difficulty in supercooling water sufficiently without initiating its crystallization. Water depresses the vitrification temperature of glycerol (184 degrees K) monotonously, and this property has been used for derivation of an estimate of its T(g). The result, 127 degrees +/- 4 degrees K (-146 degrees +/- 4 degrees C), is the temperature below which water presumably exists as a brittle, glassy substance.

摘要

水的玻璃化转变温度（T(g)）是一个难以捉摸的量，因为要充分过冷水而不引发结晶非常困难。水单调地降低甘油的玻璃化转变温度（184 开尔文），这一特性已被用于估计其 T(g)。结果是 127 开尔文（-146 摄氏度），这是水可能以脆性玻璃状物质存在的温度。
