摘要：

Electron magnetohydrodynamic (EMHD) turbulence is studied in two- and three- dimensional (2D and 3D) systems. Results in 2D are particularly noteworthy. Energy dissipation rates are found to be independent of the diffusion coefficients. The energy spectrum follows a k(-5/3) law for kd(e) > 1 and k(-7/3) for kd(e) < 1, which is consistent with a local spectral energy transfer independent of the linear wave properties, contrary to magnetohydrodynamic (MHD) turbulence, where the Alfven effect dominates the transfer dynamics. In 3D spectral properties are similar to those in 2D. (C) 1999 American Institute of Physics. [S1070-664X(99)00103-2].
