各国国家实验室实现与传递ITS—90（低温温区）的比较

The Comparison of the Low Temperature Scale according to ITS-90 among the National Laboratories

本文全面地介绍了各个国家实验室实现与传递ＩＴＳ－９０温标（低温温区）的情况，表明我国低温温标的实现方法与各国的实现方法是一致的，我国低温温标的实现水平与各国国家实验室的实现水平是处于同一水平上的．

The realizing methods of ITS-90 have been compared amongthe National Laboratories. The realizing methods and level about ITS90 of NIM is consistent with other national Iaboratories.
