摘要:介绍凝固点测量方法的研究进展。阐述了凝固点下降技术用于高纯有机物纯度定值的基本原理和适用条件,详细介绍了静力学方法和动力学方法这两种凝固点的测量方法,并介绍了两种方法在纯度定值方面的应用情况,且对两种方法的特点进行了对比,展望了凝固点下降纯度定值技术的发展趋势。 
Abstract:The research development of freezing point measuring method was introduced. The basic principles and measurement conditions of the freezing point depression method was described. Besides, principles of two freezing point measurement methods: static method and dynamic method, as well as the applications on the purity evaluation of high-purity organic compounds, were introduced in the article. Moreover, a comparison on the characteristics of the two methods was made, and the development of purity evaluation techniques of the freezing point depression was also discussed.
