太阳活动区磁场与CMEs和太阳质子事件

文中选了５ 个典型活动区， 分析了这些活动区的磁场， 与活动区相应的ＣＭＥｓ， 太阳爆发事件和太阳质子事件我们发现， 对于Ｅ ≥１０ｍｅＶ 的太阳质子事件有相应的源活动区， 源耀斑和ＣＭＥ； 活动区矢量磁场有剪切， 磁场剪切越强质子事件越强； 多数在质子耀斑发生前出现磁流浮现； 太阳１０ｃｍ 射电爆发持续时间长文中结果还佐证了Ｓｈｅａｌｙ 等的结果： Ｘ 射线耀斑的长持续时间与ＣＭＥ 的发生正相关另外，在５ 个活动区中， 有三个大耀斑发生前没有明显的磁剪切作为它们的先兆， 它们是非质子源耀斑这是Ｍｏｏｒｅ， Ｈａｇｙａｒｄ 和Ｄａｖｉｓ 的磁场强剪切是耀斑产生的必要条件的反例

MAGNETIC FIELD OF ACTIVE REGIONS, CMEs AND SOLAR PROTON EVENT

typically active regions were selected in the paper The magnetic field of the active regions,interrelated CMEs,the burst events and solar proton events were analysed We found that the solar proton events (E>=10meV) had the relevant source regions,the source flare and CME;the vector field of the active regions presented the magnetic shear,and the stronger the magnetic shear was,the stronger the solar proton event was;the most of the regions before the proton flare occurred presented the magnetic flux emergence;the relevant tenflare had long duration-time The results are consistant with the conclusion of Shealy et al :the long duration-time of X-ray bursts were directly interrelated with CMEs In addition,among the big flares in the 5 active regions,3 big flares did not have obvious precursor about the magnetic shear of the regions They were anti-examples of the conclusion resulted by Moore et al that the magnetic shear in solar active regions was necessary condition for producing flare
