摘要：

我国光源色温基准是采用两种白炽钨丝标准灯组,一组为BZ5型(6只)真空直线钨丝灯,用于2 042~2 353 K范围;另一组为BZ6型(5只)充气螺旋钨丝灯,用于2 353~2 856 K范围。该项副基准建立于1975年,为保证量值的准确、一致,1987年及1997年分别进行了两次过渡定标复查。2009年,在对原光谱辐射计系统进行了部分硬件更新和恢复以后,又对该项副基准进行了第三次过渡定标复查。仍以原灯组2 042 K的平均值为基点,对每只BZ5型和BZ6型副基准灯分别进行过渡延伸定标。对复查结果和不确定度的分析表明,此次对我国色温副基准装置的恢复改造,达到了预期目的,其测量不确定度达到了该项副基准建立时的水平。

Abstract: Two groups of incandescent tungsten standard lamps are used in the national secondary color temperature standard. One of them is a group of 6 vacuum line tungsten lamps(BZ5), which is used in a temperature range of 2 042~2 353 K. The other is a group of 5 inflatable helical tungsten lamps(BZ6), which is used in a temperature range of 2 353~2 856 K. The secondary standard was established in 1975, and had been reexamined in 1987 and 1997 respectively to ensure that the value is accurate and consistent. The 3rd transition calibration reexamination was executed in 2009 after some hardware of the original spectral radiometer system was updated and restored. Each BZ5 type and BZ6 type secondary standard lamp is extensively calibrated on the original average temperature 2 042 K. The reexamination result and uncertainty were analyzed, which showed that this restoration and transformation of the national secondary color temperature standard had reached the intended purpose and the measurement uncertainty had reached the level when it was established.
