摘要
本文简要回顾了SMM／GRS对耀斑伽玛射线的观测，并就耀斑伽玛射线的产生、伽玛射线发射的时间结构及解释、高能粒子的能谱及作用模型、高能辐射的方向性及粒子的加速机制、加速粒子的元素丰富度以及电子占优事件的性质等方面，简述了目前的研究状况。
The gammaray emissions of solar flares reflect the presence of energetic ions and nuclear reactions during nare processes. In this review paper, after brief discussion on the gammaray observations by SMM/GRS, we focus on present gamma-ray physics of solar flares, which include: the production of gammarays, the temporal behavior and its explanation, the spectra 0f energetic particles and their interaction models, the directivity of gammarays and its significance, the abundance of energetic particles, and properties of electron- dominated gammairay events
