论文摘要
太阳能活动区（AR）在通过太阳盘的过程中可能会产生多个著名的耀斑。我们研究了来自爆发活性区域的连续耀斑，并探索它们与太阳磁参数的关系。我们在这项研究中检查了六个AR，每个AR都至少高于x1.0。在本研究中采用了空间天气HMI活性区域（SHARP）来参数化ARS。我们旨在确定与爆发有关的最尖锐参数和未来实用爆发预测的基础。我们首先评估尖锐参数与连续的耀斑产生之间的相关系数。然后，我们采用天然梯度提升（NGBOOST）方法来分析尖锐参数与连续的耀斑爆发之间的关系。基于相关分析和从NGBoost返回的重要性分布，我们选择了8个与耀斑相关的尖锐参数。最后，我们讨论了8个选定参数的物理含义及其与耀斑生产的关系。
A solar active region (AR) may produce multiple notable flares during its passage across the solar disk. We investigate successive flares from flare-eruptive active regions, and explore their relationship with solar magnetic parameters. We examine six ARs in this study, each with at least one major flare above X1.0. The Space-Weather HMI Active Region Patch (SHARP) is employed in this study to parameterize the ARs. We aim to identify the most flare-related SHARP parameters and lay foundation for future practical flare forecasts. We first evaluate the correlation coefficients between the SHARP parameters and the successive flare production. Then we adopt a Natural Gradient Boost (NGBoost) method to analyze the relationship between the SHARP parameters and the successive flare bursts. Based on the correlation analysis and the importance distribution returned from NGBoost, we select 8 most flare-related SHARP parameters. Finally, we discuss the physical meanings of the 8 selected parameters and their relationship with flare production.
