摘　　要：简要回顾了近几年国际上太阳磁场研究的一些重要进展，包括耀斑与磁剪切和电流的关系、电流螺度与磁螺度、磁场拓扑性、三维磁场外推、色球磁场研究、日冕磁场研究、内网络磁元、磁流和振荡、极区磁场观测以及色球磁元观测等方面内容，同时也介绍了怀柔太阳观测站最近所取得的主要成果。自２０世纪９０年代以来，ＹＯＨＫＯＨ高分辨率的太阳Ｘ射线数据、ＳＯＨＯ的多波段大尺度观测、ＴＲＡＣＥ的高分辨太阳过渡区资料，为研究太阳磁场从内部到距离几十太阳半径处的大范围演化提供了依据．高效的空间资料结合长期的地面资料，将是进一步推动太阳磁场研究的重要手段和必然趋势。We look back briefly upon some important progresses in the solar magnetic field research, including the subjects of the relation between flares and magnetic shear and current, the current helicity and magnetic helicity, the topology of magnetic field, the extrapolation of three dimension magnetic field, chromospheric magnetic field, coronal magnetic field, intranetwork magnetic ele- ments, magnetic flux and oscillation, polar region magnetic field observation, and chromospheric magnetic field research, etc. At the same time we also introduce the main outcome of Huairou Solar Observing Station. Since the 1990's, high resolution data of X-ray observation of YOHKOH, multi-wave and large scale observation of SOHO, high resolution data of transition region from TRACE, together have provided us with the basis to probe the large distribution and evolution of solar magnetic field from the interior out to scores of solar radii distance. The high quality space data, with the coalition of long-range ground based data, will be a significant means and an inevitable tendency to propel the research of solar magnetic field.
