摘要：
为了考核和验证温度副基准装置在汶川512地震后的准确性和可靠性,对该装置进行了复现试验。通过对地震前后的数据比对分析和论证,表明温度副基准装置与震前数据保持一致。装置在地震前后的变化差值优于0.6mK,重复性优于0.2mK,满足量值传递的要求,也为我国西部地区温度量值溯源和传递的准确一致提供了保证。

Abstract: After the disastrous wenchuan earthquake happened in may 12, 2008, repetition experiments were carried out to confim the accuracy and reliability of the national secondary standard temperature device by national institute of measurement and testing technology. The comparison analyses and demonstration results of the data collected before and after the earthquake indicate that the data of the national secondary standard temperature device maintain consistent. In detail, its change differential value before and after the earthquake is less than 0.6 mK, its standard deviation is less than 0.2 mK, which show this national secondary standard temperature device can satisfy the requirements for value transfer. Thus it can support the temperature value trace and transfer in west China accurately and uniformly.
