类星体的光度函数

Luminosity Function of Quasars

主要讨论了光学选类星体的光度函数及其演化在近几年中的进展。目前在小红移范围已取得比较一致的结论。对z＞2.2，由于类星体样品的限制，对类星体光度函数的演化还存在着很大的分歧。在文中还比较了类星体光学、射电、X射线的光度函数的性质。

In this paper we give a review on recent progress in luminosity function and evolution of optical quasars. At small redshift it has reached a qulte consistent conclusion. At z > 2.2, due to the limit of QSO samples, there are still many differences of opinion in evolution of QSO litalnosity function. We also compare the properties of optical, radio and X-ray luminosity functions of quasars.
