摘要：
Because of the contamination of jets, using the size - continuum luminosity relation can overestimate the broad-line region (BLR) size and black hole mass for radio-loud AGNs. We propose a new relation between the BLR size and H beta emission-line luminosity and present evidences for using it to get more accurate black hole masses of radio-loud AGNs. For extreme radio-loud AGNs such as blazars with weak/absent emission lines, we suggest to use the fundamental plane relation of their elliptical host galaxies to estimate the central velocity dispersions and black hole masses, if their host galaxies can be mapped.
