摘要
对于赛佛特星系(文中简称WR星系),作为一种重要的活动星系的类型,求其金属丰度对我们具有重要的意义,本文将详细介绍计算HII区星系金属丰度的方法,并据此计算若干赛佛特星系的金属丰度。
The paper presents the methods of metallicity determination of galaxy, mainly for oxygen abundance. Among them, the methods based on radiation mechanism are analyzed in detail because of a firm theoretical basis. The other methods, such as dynamic metallicity, stellar photometry, image, X-Ray, stellar population synthesis, are also given as a brief introduction.
