吸积盘及其冕的结构和辐射机制是天体物理研究中的一个难点和热点，对吸积盘冕源的高能光栅光谱观测可以提供关于盘和冕的很多基本关键的物理信息。高分辨率的高能光栅光谱观测使得小质量双星中具有吸积盘冕的源（ADCs）获得非常丰富的光谱信息。我们计划通过这一类源的样本的分析，建立ADCs的共性光谱特征，为理论模型计算提供观测依据和限定合理的参数空间。我们将对已有的吸积盘冕的理论模型进行原子数据和过程、光致电离、以及辐射转移等多方面的更新和完善，从而可以完整地拟合光谱特征。对模型和观测的拟合结果的分析，我们可以获得ADCs的基本物理性质（诸如盘的大小、温度等），进一步理解ADCs的形成、加热机制以及其物质和能量的传输和转移。

We propsoe to systematically analize the high energy spectral observations of an ADCs sample, try to obtain their common charateristics. We will update our exiting theoretical model with the complete atomic database and processes, newly photionization, and radiation transfer treatments, and apply the new model to our sample. Our aim is to charaterize some basic physical properties of ADCs in terms of accretion rate, scale height, temperature, density and ionization parameters, which helps further understand their formation, heating mechalism, and matter and energy dissipation and transportation.
