类星体的特征及其红移

Characteristics and redshift of quasar

介绍了类星体的发现及主要特征；讨论了类星体的红移，并对类星体无定论的性质以及它与活动星系核的关系作了探讨．

The discovery of quasar and main properties of quasar are introduced in the first, then the debate for redshift of quasar are discussed. Lastly the mysterious properties of quasar and the relation between quasar and Active Galactic Nuclei (AGN) are explored. These objects are critical challenge to modern physics.,
