摘要

自从首次发现河外星系OH超脉泽以来，30多年(特别是近10年)中对河外星系OH超脉泽的观测和研究取得了极大的进展。到目前为止已发现106个河外星系OH超脉泽，其中包括59个较高红移的源。对河外星系OH超脉泽的观测和研究，是探测和研究其所成协的活动星系核、星暴星系的中央源和拱核盘的有效工具。主要评述对河外星系OH超脉泽的搜索、观测和理论研究现状。

　Abstract

During the thirty years since the first discovery of OH megamaser associated with external galaxies, a great progress of observations and studies for OH megamasers associated with external galaxies has been proceeded. So far 106 OH megamasers associated with external galaxies have been found, including 59 higher red-shifted ones. The observations and studies of the OH megamasers associated with AGN and starburst galaxies are the very efficient tools to investigate characteristics of their central sources and circumnuclear discs. A review on the current progress concerning surveys, observations and theoretical investigations on extragalactic OH megamaser sources is given in this paper.
