摘要

在研究光谱量的关键比较结果时，在许多情况下，参与者的结果在有限的光谱范围内系统性地偏离了关键比较参考值。我们在七个关键的光学辐射测量比较中对这些偏差进行了光谱分析。结果揭示了一个近似的结果，即平均而言，在所有研究的关键比较中，每个谐波振幅与谐波阶成反比。这一新发现提供了有关光谱相关性特征的重要信息。该结果可用于光谱积分的不确定度评估，其中未知光谱相关性的影响先前一直难以定量评估。

Spectral analysis of deviations from key comparison reference values

Abstract When studying the results of the key comparisons of spectral quantities, it appears that in many cases participants’ results systematically deviate from the key comparison reference value over a limited spectral range. We carried out spectral analysis of such deviations in seven key comparisons of optical radiometry. The results reveal an approximate outcome that, on the average, each harmonic amplitude is inversely proportional to the order of the harmonic in all studied key comparisons. This new finding gives important information on the characteristics of spectral correlations. The result can be used in the uncertainty evaluation of spectral integrals, where the effect of unknown spectral correlations has earlier been challenging to assess quantitatively.

期刊介绍： Published 6 times per year, Metrologia covers the fundamentals of measurements, particularly those dealing with the seven base units of the International System of Units (metre, kilogram, second, ampere, kelvin, candela, mole) or proposals to replace them. The journal also publishes papers that contribute to the solution of difficult measurement problems and improve the accuracy of derived units and constants that are of fundamental importance to physics. In addition to regular papers, the journal publishes review articles, issues devoted to single topics of timely interest and occasional conference proceedings. Letters to the Editor and Short Communications (generally three pages or less) are also considered.
