摘　　要：本文首先给出了近两年来我们在太阳活动区光球电流螺度的观测与研究中所取得的一些最新结果。其次，我们也展望了太阳第２３In this paper, we first summarize some observational patterns of magnetic helicity in the solar atmosphere. Then recent studies of pohotospheric current helicity in solar active regions are presented. In our studies, great interest is focussed on helicity sign in active regions, evolution of the large scale current helicity and the correlation between current helicity and flare occurrence. Finally, we list a few problems we expect to resolve in the near future.
