摘　　要：经过5年的稳定运行,ARGO-YBJ实验积累了4 000多亿个宇宙线事例样本,利用这些宝贵的数据获得了许多重要的科学研究成果。笔者将总结ARGO-YBJ对宇宙线研究领域的贡献,包括宇宙线能谱、成分和各向异性等传统宇宙线课题,还包括许多相关的观测研究,如探索利用宇宙线监测太阳的活动,预报由太阳巨大耀斑引发的地磁暴,探索雷暴与高能宇宙线在大气中的级联反应之间的关联等。随着计划中更灵敏的新一代LHAASO实验的逐步实现,文中所介绍的所有研究都将得到显著的提高,可能在其中某些研究方向产生突破。Being smoothly operated for 5 years, the ARGO-YBJ experiment collected 0.4 trillion cosmic ray event samples. Many scientific goals have been achieved based on the very important data base. Here in this article, we summarize all major contributions to cosmic ray related researches, including conventional measurements such as cosmic ray energy spectrum, composition and anisotropy. The researches also cover many non-traditional topics such as the monitoring of solar activity using Galactic cosmic rays, forecasting large geomagnetic storms induced by huge flares of the sun, exploring the correlation between thunderstorms and extensives air shower of cosmic rays and so forth. With the progresses of the future experiment LHAASO, all researches reported in this paper will be greatly enhanced using the most sensitive new generation apparatus. Breakthrough may be expected in some of the topics.
