【摘要】 本文介绍我国在紫外辐射度计量领域的新进展,以及光谱辐射照度国际关键比对CCPR-KIa和UVA探测器照度响应度国际比对的相关内容。1990年的光谱辐射照度国际比对表明,我国在紫外波段与国际参考值之间的偏差高达12%,在近红外波段的偏差达5%,采用新技术新方法,对我国的紫外辐射度国家基准进行全面技术改造,改善了基准的测量不确定度。在2004年新的国际关键比对中,我国在紫外和近红外波段的测量结果与国际平均值的一致性优于1.5%。本文对UVA探测器照度响应度国际比对中的技术细节和比对方法进行了详细的讨论。更多还原

【Abstract】 Abslraet New development for UV radiation measurement, international comparison of spectral irradiance from 250 to 2500nm CCPR-K1a and international comparison of irradiance responsivity of UVA detectors are described in this paper. In 1990 international comparison, the discrepancy between our result and the international reference value was more than 12% in UV wavelength and 5% in infrared wavelength. Measurement uncertainty of the national primary standard of spectral irradiance was promoted greatly because new technology and methods are applied. The 2004 comparison shows our result is consistent with the reference value within 1.5% in both UV and infrared wavelength. In addition, the methods used for measuring the irradiance responsivity of UVA detectors are described and compared in this paper.更多还原
