| 摘 要： | 本文讨论了有拱星壳层的ＡＧＢ星的红外辐射的双黑体模型并给出了便于似合某些ＡＧＢ星的红外辐射的双黑体模型并给出了便于拟合某些ＡＧＢ星的红外观测数据的数学表达式，应用Ｔａｙｌｏｒ级数方法解决了这一复杂非线性模型拟合的困难，从而得出了一些ＡＧＢ星较合理的中心星及壳层的色温度和红外能谱曲线。

| Abstract: | It is important and difficult for the fitting of the infrared spectrum of AGB stars. This is of vital importance to the determination of many physical parameters. In this paper, the double-blackbody model for the infrared spectrum of AGB stars is built, and by using Taylor series method, the difficulty of this complex non-linear model fitting is solved. Taking this fitting method, we get the more accurate color temperatures of the central stars and dust shells of AGB stars, and the more reasonable infrared spectruni curves. |
