提出了一个假设活动星系核（AGN）中央发动机附近存在冷密云的模型。探讨了这种云对观测光谱的影响。结果表明，该模型与已被广泛研究的Seyfert核的复杂光谱和光变行为是一致的。与其他提出的模型的结果进行了比较。现有的观测证据似乎支持“云模型”。"
A model is presented which assumes the existence of cold dense clouds near the central engine of Active Galactic Nuclei (AGNs). The effects of such clouds on the observed spectrum are explored. It is shown that this model is consistent with the complicated observed spectra and variability behavior of most extensively studied Seyfert nuclei. The results are compared with other proposed models. The existing observational evidence appears to support the "cloud-model."
