| 摘 要： | 高温黑体温度的测量水平将直接影响光谱辐射度量值的不确定度。我国的高温温标截止于 2 2 0 0℃。确定2 2 0 0℃以上范围内的温度必须进行温度延伸。从Planck公式的定义出发 ,推导出用单色亮度比较法进行温度延伸的原理和方法。在国家光谱辐射度基准改造中 ,该方法被用来确定高温黑体的温度。实验证明 :使用参考灯替代法能够有效消除探测器灵敏度漂移带来的误差。此外 ,旁证实验用来验证该方案的可行性。

| Abstract: | The temperature of high temperature blackbody is one of the key factors that affect the measurement uncertainty of spectral radiometry. Monochromatic radiance ratio method using to extend high temperature scale for blackbody is described. A lot of experiments proved the correctness of this method. The measurement error caused by the variability of the photomultiplier tube was reduced by using a reference lamp. |
