| 摘 要： | 太阳磁场望远镜安装了CCD图象接收处理系统后,得到许多精细结构的两维、实时磁场、速度场图。本文对其中观测的两群黑子,做耀斑磁场、速度场分析。在此基础上指出,异极性磁区相互渗透是普遍存在的,耀斑亮核均发生在异极性磁区相互挤压的前锋。这就为挤压无力场耀斑模式提供了有力的证据。同时发现,在耀斑发生的区域,流场的方向是向下的。

| Abstract: | The fine structure of magnetic fields and line-of-sight velocity fields have been obtained with CCD camera and image processing system since June, 1987. They are all two-dimensional and real time graphs. So far, several big flares have been observed with this system in three active regions. The penetration of different polarities have been found to exist universally on the basis of the analysis of observation. The bright kernels of flares were located in front of squeeze of different polarities. It provides an evidence for the flare model of squeezing force free magnetic field. |
