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。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 Ha 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.
