| Abstract: | According to hard X-ray temporal, spectral and spatial characteristics, solar flares are identified as type A, B and C. In this paper, the spatial structure and height distribution of hard X-rays in flare loop with non-uniform cross section are analysed. The formation and characteristics of hard X-ray sources for the three type flares are discussed. It is shown the structure and distribution of hard X-ray sonices are closely related with the parameters of magnetic structure of flare loop, density of background plasma and spectrum of non-thermal electrons. |
