中文摘要	本文从耀斑高能电子束流与太阳大气相互作用产生硬X射线辐射的基本事实出发,根据观测资料,提出了一个流量与能谱同步变化的注入函数模型,研究太阳大气密度对耀斑硬X射线时间响应.理论计算与观测事实基本一致.
英文摘要	From the well-known fact that the solar hard X-rays are produced by an energetic electron beam impinging on solar atmosphere,and based on the observational fact that there are good correlation between the solar hard X-ray flux and energy spectrum,in this paper,a source function with synchronous variation between the injecting electron beam flux and spectrum index is proposed,and some calculating results about hard X-ray temporal properties in solar flares are obtained. These results show:high energy delay and emission broadening are two manifestations of solar hard X-ray temporal properties in the nonthermal bremsstrahlung process,and the relation between them is very dominant.The lower the density of solar atmosphere where hard X-rays produced,the more distinct for high energy delay and emission broadening of solar hard X-rays.
