摘要：

This work is based on hard and soft X-ray observations from the YOHKOH satellite. We investigate are example of an arcade flare, for which the arcade channel is seen in soft X-rays as a long bright filament. We have found that: (1) Energy can efficiently flow along the arcade channel from the very beginning of a fare. (2) During flare evolution a few kernels of hard X-ray emission develop along the arcade channel. Clearly, they are new, additional sources of the flare energy release. A probable scheme of formation of such hard X-ray kernels is briefly discussed. (C) 1997 COSPAR. Published by Elsevier Science Ltd.
