摘　　要：利用自行研制的紫外CCD光学多道分析器对太阳紫外辐射光谱进行探测。对太阳紫外辐射光谱进行的初步分析表明:太阳紫外辐射在一天内早晚小中午大,与太阳天顶角(SZA)变化呈相反相关;不同波段的辐射量不同,长波段的辐射量一般比短波段的辐射量大;太阳紫外辐射光谱强度受云的影响而衰减,且衰减依赖于波长,随波长的递减而减小。紫外CCD光学多道分析器不仅能够用于监测太阳紫外辐射总辐射量,而且可以精确分析各波长的辐射量,以及在不同大气状况下各波长辐射量的相对变化情况。We report a new type of ultraviolet（UV） CCD optical multi-channel analyzer and its application for detecting solar ultraviolet irradiance spectrum.Primary analysis on detection results of solar UV irradiance spectrum indicates that in the morning and in the afternoon the irradiance of solar UV is smaller than that at noon,and reverse correlates to the change of solar zenith angle （SZA）.Radiation of different bands are different：long-wave radiation is generally higher than short wave radiation.Solar UV radiation spectral intensity is bated by the effects of clouds,and the attenuation depends on the wavelength and decreases with decreasing wavelength.UV-CCD optical multi-channel analyzer can be used to monitor the total amount of solar UV radiation,and to analyze the amount of radiation at all wavelengths and the relative charges of radiation at different wavelengths in different atmospheric conditions.
