The Broad-line Region in Active Galactic Nuclei (Ⅱ)

Xue Suijian; Cheng Fuzhen(Center For Astrophysics, University of Science and Techsnology of China, Helei 230026ShaanXi Astronomical Observatory The Chinese Academy of Sciences, Lintong 710600)  
One of typical characteristics of active galactic nuclei (AGNs, except BL Lac objects) is that strong and broad emission lines apear in their spectra. It is therefore that the broad-line region (BLR), from which broad emission lines come, affords us a unique and important probe of the physics of AGNs. This paper will discuss the various physical conditions of the BLR, review the recent progress and situation in the observations and theoretical studies of the BLR. In paper (Ⅱ), our interests will centre on the size,geometrical structure and kinematics of the BLR.
