Quasars are a class type of the most characteristics in active galactic nuclei (AGN). The colorful observation and extreme physical characteristics reflects that the structure and physical process of quasars are very complex. The study of central black hole accretion and jets of Fermi quasars will solve the major problems of the structure, evolution, energy radiation mechanism and the formation of jets, transmission and acceleration for Fermi quasars, and have great significance to understand the nature of accretion and jets of Fermi quasars. This project combines the observational and theoretical to research the central black hole mass, accretion and jets of Fermi quasars. By spectral data and optical variability to calculate black hole mass, and analyze the difference between the multi-band observation data of optical variability and the central black hole, jets and accretion for Fermi selected quasars, the peak time delay between radiation optical variability of each peak, contrast observation value and theoretical value of the delay timescale between the optical variability in each band. Using multiband observed data to analyze the discussion of optical variability and accretion theory model, validate the model of “black hole +accretion disks + jet", and limit some parameters, such as the central black hole mass, producing area of disturbance on accretion disks, etc. From some physical parameters to find Eddington accretion and intrinsic bolometric luminosity (Lbol), core-dominance parameters are the physical parameters of driving evolution of AGN. Analyze the relationship between variability timescale at multiband, accretion and jets. Use the statistical analysis of the optical variability at multiband to study radiation structure and mechanism in jets. And estimate the physical parameter of radiation region, study the radiation process in jets.
