| 摘 要： | 通过复现温度间隔相近的3个高温固定点黑体,可以实现0.65 μm高温计在900～2 500 ℃、0.9 μm 高温计在600～2 000 ℃范围内的内插,不确定度最好水平分别达到0.3～1.2 ℃和0.3～0.6 ℃(k=2)。通过其他非分度固定点黑体和高温变温黑体的验证,2种波长高温计与高温基准温标的一致性优于0.1 ℃。应用高温固定点可以满足精密光电高温计接近国际最高水平的校准,提升高温校准的不确定度水平。 |

| Abstract: | A 0.65 μm and a 0.9 μm pyrometers are interpolated by three high temperature fixed points (HTFPs),the best uncertainty is estimated 0.3 ～ 1.2 ℃ (k =2) in 900 ～ 2 500 ℃ for the 0.65 μm pyrometer and 0.3 ～ 0.6 ℃ in 600 ～ 2 000 ℃ for the 0.9 μm one separately.The pyrometers are also verified by the other fixed points and high temperature blackbody against the primary pyrometer,and the agreement is better than 0.1 ℃.The HTPFs can be applied in the precise calibration of pyrometers to improve the level of measurement uncertainty in high temperature range. |
| Keywords: | metrology temperature scale pyrometer high temperature fixed point interpolation uncertainty |
