摘要：
The influence of small-scale turbulence on large-scale perturbations is studied in the model of 3-D electron magnetohydrodynamics (EMHD), in which the magnetic field has all three components. it is shown that in addition to positive turbulent viscosity and an analogue of alpha-effect caused by helicity of turbulence, which are typical to 3-D EMHD turbulence, such 2-D turbulence results in turbulent resistivity, which is caused by anisotropy of turbulence and can be negative.
