摘要
本文通过介绍一种计算杂质在复现各定义固定点温度时引起的偏差的方法 ,从实验及理论分析计算的角度讨论了在高纯金属凝固 (或熔化 )过程中 ,样品中的杂质对相变温度的影响。
Impurities influence phase transition temperatures and, for many materials, impurities are the source of the largest uncertainty component in the realization of fixed points at the highest levels of accuracy. This paper recommends a method to estimate the error due to impurities on fixed point temperatures. In the end it makes the comparison between the calculation and previous results on the research report.
