摘要

摘要: 通过对0°W-39°W，40°W-70°W，71°W-90°W经度范围内太阳质子事件与太阳耀斑的相关性计算分析，发现太阳质子事件与太阳耀斑的相关系数依赖于经度.太阳耀斑积分与地球磁链接区域（40°W-70°W）太阳质子事件强度的相关系数最大.相关系数的这种特点与耀斑加速粒子的最大流量只出现在磁链接区域的特征相吻合.计算结果表明，太阳耀斑对太阳质子事件具有贡献，即耀斑对E ≥ 10MeV的质子加速有贡献.耀斑和CME在磁链接区域对太阳质子事件的贡献相同，这说明太阳质子事件是混合型事件.

Abstract: The Correlation Coefficients (CC) between the time integral of solar Soft X-Ray (SXR) flux and the intensities of Solar Proton Events (SPE) in 0°W-39°W, 40°W-70°W and 71°W-90°W longitudinal areas have been calculated. The results show that the CC has its largest value. The property of CC is consistent with the concept that the largest flux of flare-accelerated particles can only be observed in the longitudinal area well magnetic connected with the observer. The results suggest that solar flares contribute to the production of SPE, namely that E ≥ 10MeV protons may be accelerated by the concurrent flares at the early phases of SPE.
