摘要

总结了近期对LINERs的一些研究结果，通过对LINERs在各波段上表现出的一些特性讨论了LINERs的几种模型，重点讨论了LINERs是典型的AGN的可能性。结论为具有如下至少一个特征的LINERs可能是典型的AGN ：(1)有宽的发射线成分；(2)有双峰宽Hα线发射；(3)有硬的X射线的连续谱；(4)有点状紫外源；(5)有致密射电核和喷流。

Abstract

This is a review paper of LINERs. We collected the research results of LINERs in multi-band. The models presented different characters in each wavelength band have been discussed. It is important to evaluate the probability of LINERs as typical AGNs. The LINERs classified as typical AGNs at least have one of the following physical characters: (1) the presence of broad emission-line region;(2) the presence of double peak broad Hα line; (3) the presence of hard X-ray source; (4) the presence of point-like ultraviolet source; (5) the presence of radio core and jets.
