摘要：
We investigate anisotropic magnetohydrodynamic turbulence, in presence of a constant magnetic field, using direct numerical simulations. A method of decomposing the spectral space into ring structures is presented and the energy transfers between such rings are studied. For large values of the constant magnetic field, the total energy transfer appears to be dominant in the direction perpendicular to the mean magnetic field. The linear transfer due to the constant magnetic field also appears to be important in redistributing the energy between the velocity and the magnetic fields.
