Scientific paper
From the basic magnetohydrodynamics equations, the accretion disk model with a quasi-dipole magnetic field is discussed. The result shows that the introduction of the quasi-dipole magnetic field influences the configuration, luminosity and the accretion ratio of the disk. The influence on the luminosity is realized by means of changing the configuration of the disk, and makes the disk thicker. The funnel structure, which is narrower and more gradient, is formed by the disk configuration change. This structure is more appropriate to explain the high collimated jet of quasars, and to predict the existence of the one-sided jet and the asymmetric jet.
