太阳质子事件、双带耀斑及日冕物质抛射

SOLAR PROTON EVENT,TWO-RIBBON FLARE AND CORONAL MASS EJECTION

本文统计了第２２ 太阳活动周期间（１９９１ ～１９９５ 年） 发生的２５ 个太阳质子事件与太阳耀斑及日冕物质抛射（ＣＭＥ） 事件的关系 统计结果表明， 所有的太阳质子事件都与耀斑发生相关， 除２ 个质子事件（１９９４１０２０ 和１９９５１０２０ 日发生的太阳质子事件） 与ＣＭＥ发生无关， 其余质子事件也都与ＣＭＥ 相关 值得注意的是， 与质子事件相关的耀斑有１６ 个是双带耀斑， 其中包括与ＣＭＥ无关的２ 个事件的耀斑， 占总数的６４ ％  上述统计结果证实了无论是太阳耀斑， 还是物质抛射，

The relations among solar proton event,solar flares and coronal mass ejection (CME) events were analyzed These solar events were recorded from 1991 to 1995 of the 22nd solar cycle 25 solar proton events were associated with solar flares and 23 of them were associated with CME events It was noticed that 16 flares associated with solar proton events were two-ribbon flares It means that 64% solar proton events studied were associated with two-ribbon flares Above mentioned statistics show that solar flare and coronal mass ejection play important roles in the occurrence of solar proton event And when CME event takes place associated with two-ribbon flare,the probability of occurrence of a solar proton event is higher It is possible that part of CMEs and solar flares may be produced by reconnection of a magnetic field and reconnection of a magnetic field is an important condition for occurrence of solar proton event
