Observation and analysis of solar spectral radiation in solar eclipse at Mohe

The observation data of solar UV, visible, infrared 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, infrared and total radiation were similar, their energy deficits and percentages of energy deficit increased with increasing area of the sun's surface covered by the moon's umbra, and reached the maximum at the maximum of the solar eclipse. The energy losses of solar UV, visible, infrared and total radiation in solar eclipse were 0.09, 0.55, 0.72 and 1.28 MJ/m(2), respectively. There were still good relationship among solar UV, visible, infrared and total radiation during the solar eclipse.
