摘要
The thermodynamic consistency of the temperature scale PLTS-2000 has been checked with new measurements using a noise thermometer, which is assumed to indicate thermodynamic temperature, and a platinum nuclear magnetic resonance thermometer, which is assumed to follow a Curie law. The different results are interpreted in terms of the properties of these thermometers, and with supporting calculations using the specific heats of solid and liquid He-3. On this basis, it is possible to specify uncertainty limits of the scale with respect to thermodynamic temperature.
