    摘要:

    针对气象用温度计量标准,量值传递的准确性与可靠性偏低问题。设计了二等铂电阻计量标准装置的校准结果的验证方案。该方案以某省级二等铂电阻计量标准装置的校准结果为例,通过传递比较法和同级比对法对进行了验证。结果显示,该装置与高等级计量标准装置,对应校准结果的绝对偏差值均小于0.019 ℃,满足传递比较法的要求;该装置与参与比对的4项计量标准装置,对应校准结果的加权算数平均值的绝对偏差均小于0.007 ℃,也满足同级比对法的要求。因此,两种方法均验证通过。结果表明,该二等铂电阻计量标准装置能获取准确的量值传递数据,该方案能确保气象用温度计量标准,量值传递的准确性与可靠性。

    Abstract:

    In response to the low accuracy and reliability of temperature measurement standard for meteorological purposes, the accuracy and reliability of quantity value transmission are low. A verification scheme for the calibration result of the second-grade platinum resistance measurement standard device has been designed. This scheme takes the calibration result of a provincial second-grade platinum resistance measurement standard device as an example and verifies it through transfer comparison method and peer comparison method. The results show that the absolute deviation values of the corresponding calibration results between the device and the high-level measurement standard device are both less than 0.019 ℃, meeting the requirement of the transfer comparison method. The absolute deviation of the weighted arithmetic mean of the corresponding calibration results between this device and the four measurement standard devices participating in the comparison is less than 0.007 ℃, which also meets the requirements of the peer comparison method. Therefore, both methods have been validated. The results indicate that the second-grade platinum resistance measurement standard device can obtain accurate quantity transfer data, This scheme can ensure the accuracy and reliability of meteorological temperature measurement standard and quantity value transmission.
