论文摘要
自关键比较CCT-K2以来，仅对低温固定点实现的比较只有很少的比较，无论是双边的（三个仍在待处理）还是多边（两个三边）。由于即将进行的一般性随访不太可能，因此，最不仅需要进行任何双边比较，不仅是关键比较，因此也欢迎提供证据证明与ITS-90实现的实验室持续的热量表能力相比。在2018年创建LNE-CNAM和INRIM之间的流体计量福音派联合研究实验室的创建后不久，两个实验室同意在13 K和273 K之间的所有低温固定点上进行双边比较，包括两个氢气蒸发温度，包括5次氢气量的platinimans-demtery platinims-thermum paltinum paltinum paltinim pathinim pathinim pathery pathinim pathim pathinim ins pathim and pathim and pathin demptery ins themers tempory ins tody 0 3. 3. 3. 3. 3. 3. 3. 3. 3. 3. 3. 3. 3.结果在此报告，并在联合不确定性中显示出实质性的协议。
Since Key Comparison CCT-K2, only few comparisons on realizations of cryogenic fixed points have been carried out, be they bilateral (three, of which one still pending) or multilateral (two trilateral). Since a forthcoming general follow-up is unlikely, any bilateral comparison, not only key comparisons, is most welcome to provide evidence of the continuing thermometric capabilities of the laboratories involved in the realization of the ITS-90. Not too long after the creation in 2018 of the Joint Research Laboratory for Fluid Metrology Evangelista Torricelli between LNE-CNAM and INRIM, the two laboratories agreed to perform a bilateral comparison at all the cryogenic fixed points of the scale between 13 K and 273 K, including the two hydrogen vapour-pressure temperatures required for the full platinum resistance thermometer range 3.3.1 of the ITS-90. The results are reported here and show a substantial agreement, within the combined uncertainties.
