Space Observation and of the Study Sun.I.Observation and Study of Solar Electromagnetic Radiation

Many new observational phenomena on the sun are revealed by the space observation which opens up a new way.The space observation has some advantages of all wave bands, all time, all positions and of unatmospheric agitation, unscat tered light.The space observation successes in solar long wave radio, X-ray, EUV.research results from those observations are investigated in this paper.The bursts in these wave bands including optical wave band all are caused by the electromagnetic radiation, which o riginates f rom interaction between the accelerated energetic elect rons in solar atmosphere and the solar plasma.Their energy could be 1/4 of all energy of a flare, i.e.10²⁵J.
