结论摘要：

太阳剧烈活动(主要是耀斑和日冕物质抛射)是空间灾害性扰动的源头和决定性因素。本项目着重研究太阳活动体的结构和演化，研究太阳剧烈活动的输出和诊断、它的形成机理。五年来，顺利地完成了原定的研究计划全面建成太阳射电宽带动态频谱仪，改进了南京大学60厘米太阳塔和紫台二维成像光谱仪等多种设备并投入观测，获得了一批宝贵的观测资料，发现了全频段的漂移脉动结构、微波斑马纹结构、耀斑红外连续发射等一批重要的新现象；通过数值模拟，提出了EIT波和Ellerman炸弹等产生的新机制，提出了由磁流浮现触发日冕物质抛射的新模型和耀斑的统一模型,提出了一个从观测下折双幂律谱推求加速电子低端阈能的定量新方法；得到加速电子的低端阈能可以远大于以前所认为的20 keV；提出用非热电子轰击模型来解释边缘耀斑的宽谱线、用膨胀模型来解释白光边缘耀斑中观测到的特大加宽He I 10830线轮廓；提出了一个定量估计日冕物质抛射向行星际空间输出物质与磁场的方法；提出用神经网络方法作太阳质子事件警报和短期预报，用相似周方法作太阳周的预测；定期发布太阳活动预报，为联测提供了基础等。
