Abstract
The observation data of solar UV, visible, IR and total radiation during the 9 March 1997 solar eclipse at Mohe have been analyzed, results are the following: during period of solar eclipse, variation trends of solar UV, visible, IR and total radiation were similar, their energy deficits and percentages of energy deficit increased area of the sun 's surface covered by the moon's umbra, and reached the maximum of the solar eclipse. The energy losses of solar UV, visible, IR and total radiation in solar eclipse were 0.09, 0.55, 0.72 and 1.28 MJ/m2, respectively. There were still good relationships among solar UV, visible, IR and total radiation during the solar eclipse.
