摘      要：We extend the research by Lubow and Pringle of axisymmetric waves in accretion disks to the case where self-gravity of disks should be *** derive and analyse the dispersion relations with the effect of *** show that self-gravity extends the forbidden region of the wave propagation:for high frequency p-modes,self-gravity makes the wavelength shorter and the group velocity larger;for low frequency g-modes,the effect is opposite.
