三种类型的质子耀斑

根据SMM卫星观测资料,分析了GRL,PE和GRL/PE三种类型质子耀斑在硬X射线辐射特征上的差异。结果表明,存在的差异与粒子加速区(或作用区)分别处于不同的日面高度有关。 

THREE CLASSES OF PROTON FLARES

The nuclear γ-ray line (GRL) and the proton event (PE) observed in interplanetary space are direct evidences that protons and heavy ions are accelerated to energies above several MeV per nucleon for solar proton flares。 Solar Hard X--ray properties obtained by SMM satellite show there are three classes of solar proton flares: GRL, PE and GRL/PE。 The results indicate the different behavours respect to the hard X--ray properties for the three classes of proton flares seem to be relative with the different height distribution of energetic particles acceleration region (or active region) for the GRL, PE and GRL/PE proton flares。
