摘　　要：本文在非均匀截面耀斑环的模型下，分析了硬Ｘ射线辐射的空间结构和高度分布，讨论了Ａ，Ｂ和Ｃ三类耀斑硬Ｘ射线源的形成和特征．结果表明：硬Ｘ射线源的结构和高度与耀斑环磁场结构。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.
