太阳耀斑区磁场和电流研究的一些新进展

Some Progress in Researches on Magnetic Fields and Electric Currents of Solar Flare Regions

在太阳耀斑区磁场和电流研究方面，文中将着重介绍太阳横向磁场方位用的确定、太阳活动区磁场的非势性表示、太阳耀斑前后的活动区磁场变化、以及耀斑核块与活动区纵向电流密度极大点位置的关系等几个重要问题的研究现状。鉴于这些问题正是国内同行颇感兴趣和工作较多的领域，文中将强调国内学者在这些课题中的研究进展。

In respect of the researches on the magnetic fields and electric currents of solar flareregions, this paper is to be concentrated in the review of some important problems, suchas the determination of the azimuth of solar transverse magnetic fields, the presentationof the non-potentiality of magnetic fields in solar active regions, the variations ofmagnetic fields before and after solar flares, as well as the location relations betweensolar fiare kernels and peaks of longitudinal electric current densities. As these subjectsare particularly interesting to and studies by the solar researchers in China, theircontributions in these fields are emphasized in the paper.
