| 摘 要： | 介绍了近年来Ｓｅｙｆｅｒｔ领域中关于分子环（ｔｏｒｕｓ）研究情况和现状。分子环模型的提出源于２型Ｓｅｙｆｅｒｔ星系核的光学偏振观测的结果与传统的１型Ｓｅｙｆｅｒｔ核的观测特征的相似性。在ｔｏｒｕｓ结构存在的假设下，讨论其对观测的作用，阐述了ｔｏｒｕｓ可能的结构和演化及其在Ｓｅｙｆｅｒｔ统一模型中的重要地位。还讨论了ｔｏｒｕｓ的遮挡、束流效应和由此造成的多波段观测特性，着重介绍了散射效应及其造成的偏

| Abstract: | The study of the molecular torns in seyfert galajxies is introduced. This structure is suggested from the similarity between the polarization measarements of Seyfert 2 and the observational data of Seyfert 1. With torns structure hypothesis, we discuss its effects on observational results,describe the possible structure and evolution of torns as well as its importance in the unified model. The effects of obscuring and beaming, and multi-waveband properties caused by these effects are described. The scattering effect and the observed polarization induced by this effect are emphasized. |
