漠河日食期间太阳分光辐射的观测及分析

OBSERVATION AND ANALYSIS OF SOLAR SPECTRAL RADIATION IN SOLAR ECLIPSE AT MOHE

通过对漠河地区１９９７年３月９日日食过程太阳分光辐射和总辐射观测资料的分析，表明在日食过程中，紫外辐射、可见光辐射、红外辐射与总辐射的变化规律基本上一致，紫外辐射、可见光辐射、红外辐射与总辐射辐照度的亏损以及亏损的百分率都随着食分的增大而增加，至食甚时达到最大。日食过程中，紫外辐射、可见光辐射、红外辐射和总辐射能量亏损值分别为０．０９、０．５５、０．７２、１．２８ＭＪ／ｍ２。日食过程中，紫外辐射、可见光辐射、红外辐射与总辐射之间仍存在很好的相关关系。

The observational data of solar UV,visible,infrared and total radiation during the 9 March 1997 solar eclipse at Mohe are analyzed,the results are the following:during the period of solar eclipse,the variation trends of UV,visible,infrared and total radiation is similar,their irradiance deficits and percentage of irridiance deficits increase with increasing area of suns surface covered by moons umbra,and reach the maximum at the middle of solar eclipse.The radiance exposure losses of solar UV,visible,infrared and total radiation in solar eclipse are 0 09,0 55,0 72 and 1 28MJ/m 2,respectively.There are still good relationship between UV,visible,infrared and total radiation in solar eclipse.
