摘要 通过数值模拟研究了欧姆定律中的Hall效应修正对MHD湍流的能量衰减的影响。在低或没有磁螺旋性约束的情况下推导出了t–1能量衰减律。 The Hall effect, correction to Ohm's law, on the energy decay of MHD turbulence is studied by using high-resolution numerical simulations, and the energy decay law with t-1 exponent is derived for the case of small or zero magnetic helicity.
