| 摘 要： | 为了解释致密天体高能辐射的时延现象和能谱等特征,多种致密天体X射线辐射源的理论模型先后被提出。但是,目前尚没有一种模型能够完全解释X射线的高能辐射现象,即现有的理论模型还不够完善。通过对X射线辐射源时延现象和短暴半高宽随能量变化这两个特性的讨论,并尝试将Cyg X-1的观测结果与康普顿化模型进行比较,对原模型给出更多的限制从而建立更为合理的新模型。

| Abstract: | In order to explain the phenomenon of time lags and the characteristic of energy spectra that is high energy radiation from compact objects,many theoretic modes of X-ray source have been put forward.By far there are not any the model that can explain the phenomenon of time lags completely,namely,the theoretic modes are not consummate yet.Two characters are studied about temporal character of X-ray source and FWHM with energy,and the observation result of Cyg X-1 have been tried to compared with Compton Models.It gives more confine to build more logical new models. |
