摘　　要：水的三相点是热力学温度的唯一基准点,也是1990年国际温标(ITS-90)定义的最基本的、及其重要的固定点。水三相点的复现是通过水三相点瓶的冻制和保存来实现的,本文介绍了一种快速且实用的水三相点瓶冻制方法,并阐述了此种方法的优点。The triple point of water is the only reference point of thermodynamic temperature,and it is also the basic and important fixed point of ITS-90.The reproduce of the triple point temperatures is realized by freezing water triple point cells.This paper introduces a method of freezing water triple point cells,and this method is quick and practical.The advantages of this method are also discussed.
