LEVELS OF SOLAR SOFT X-RAY BACK GROUND AND ENHANCED EMISSIONS WITH IMPORTANCE X

摘要: 本文根据1986年1月-1992年12月期间,130个1-8Å的X级别的X射线事件与相应背景发射水平所作的分析,发现90%以上的X级X射线事件,都发生在X射线背景发射≥C1(10-6W／m2)水平上,这一统计规律,可从耀斑加速的非热电子对色球等离于体的加热得到合理的解释.Abstract: During the periods of January, 1986-December, 1992, 130 solar soft X-ray events with importance≥ X1 at 1- 8Å wavelengths reported and the corresponding background emissions are analyzed. And it is found that more than 90% of X-ray events with importance ≥X1 appeared at the level≥C1 of background emission. Such a statistical rule may be interpreted as the result that the nonthermal electrons accelerated by solar flare to heat chromosphere plasma.
