主　　题：thermodynamic temperature kelvin 

摘      要：The unit of thermodynamic temperature,the kelvin,is one of the seven base units of International System of *** international temperature scaIe of 1990 (ITS-90)is a practical temperature scale used worldwide to approximate thermodynamic tempera- ture T by ITS-90 temperature *** primary thermometry calibration facilities based on thermodynamic temperature standards are the foundation of ITS 90 and temperature measurement in a *** has developed primary thermometry in the temperature region down to the neon triple point 24.5561 K estimated by ITS-90,but it has not yet set up any primary thermometry at lower temperatures.
