题目：Spatially-resolved observations of the sources of hard X-ray pulsations and their links with the magnetic structure in solar flare regions

　　报告人：Dr. ZIMOVETS IVAN （Space Research Institute (IKI) of Russian Academy of Sciences, Moscow, Russia)

　　摘要：In this talk, I would like to summarize our recent results on the topic of multiple hard X-ray bursts in solar flares (based on the RHESSI observations), their links to magnetic structure (flare arcades, magnetic flux ropes) and distribution of vertical electric currents in parent active regions (based on the HMI/SDO data).
