摘要

窄线 Seyfert 1 型星系(NLS1)作为活动星系核的一个小类，由于其X射线等高能波段上独特的观测特征，近年来越来越受到天文学界的广泛关注。详细描述了NLS1在观测及理论上的一些新进展，并对其主要模型作了较细致的讨论。

Abstract

Narrow-Line Seyfert 1 Galaxies (NLS1s), as one subclass of Active Galactic Nuclei (AGNs), are more and more widely paid attention by astronomers because of their special observational characteristics in X-ray band. The progress of the observations in NLS1s is described, and some main models are discussed in detail.
