低温温度计标定精度影响因素的研究

Investigation of the Influencing Factors for Calibration Precision of Low Temperature Sensors

在托卡马克核聚变实验装置中 ,装置的热负荷计算、导体超导性能和运行稳定性都与运行温度有很大关系 ,因而要求低温的温度测量有较高测量精度。文中主要讨论低温温度计在标定过程中各种因素对标定精度的影响 ,并提出一系列的解决办法 ,取得了好的标定结果 ,满足了工程的需要。

In the tokamak, heat load of the device, the superconducting conductor's performance and the operating stability, all of these are related to the operating temperature in the tokamak experimental device for nuclear fusion, so we need the high measure precision for Low Temperature Sensors. We have studied on the influencing factors for the calibration precision of Low Temperature Sensors in the calibration process, and put forward the resolved ways. We have acquired good results of calibration, and that will have met engineering's demands.
