【摘要】：本文統(tǒng)計(jì)分析了2009年地面宇宙線觀測數(shù)據(jù)與ACE衛(wèi)星宇宙線觀測數(shù)據(jù)的通量變化.研究發(fā)現(xiàn),2009年地面宇宙線中子強(qiáng)度比第19~23活動(dòng)周的太陽活動(dòng)極小年平均高出3%以上,達(dá)到了近50年的最大值;ACE衛(wèi)星部分重粒子在2009年的通量比1998年平均高出30%以上,并且Z≥10,100~400 MeV/nuc的粒子通量比1998年高出52.2%,這些分析結(jié)果表明2009年宇宙線通量異常高.
[Abstract]:In this paper, the flux variation of surface cosmic ray observation data and ACE satellite cosmic ray observation data in 2009 is statistically analyzed. It is found that the neutron intensity of the surface cosmic ray in 2009 is more than 3% higher than that of the solar activity minimum in the 1923 active cycle. The flux of some heavy particles of ACE satellite in 2009 is more than 30% higher than that of 1998, and the flux of particles with Z 鈮，
