【摘要】 耀斑Υ射线研究近年来有了飞速的发展，这主要是得益于康普顿Υ射线天文台、GRANAT卫星和阳光卫星的新观测，以及对GRS／SMM资料的详细分析。简要概括了耀斑Υ射线观测和研究近年来获得的主要进展，其中包括：超长时间Υ射线暴、边缘强2．223MeV事件、大于10MeV耀斑日面分布、Υ射线谱和连续谱、粒子的加速机制等，并展望未来的发展趋势。更多还原

【Abstract】 Due to the new observations obtained by CGRO, GRANAT, YOHKOH, and other satellites,and due to detailed analyses based on the data of the GRS/SMM, the studies on solar flare Υ-rayshave developed greatly. This paper summarizes the recent progresses in both observations and studies, which include: very long duration Υ-ray bursts; intense 2.223 MeV line event off the solar limb; the hello-distribution of the Υ-ray flares with an emission above 10 MeV; the spectroscopy of solar Υ-rays (lines plus continuum); the acceleration mechanisms; and so on. At last we prospect the near future of the subject.更多还原
