Abstract
In this paper it is analyzed the propagation of large amplitude Alfvén waves in partially ionized plasmas (PIP) when electronic pressure, Hall and ambipolar terms of Ohm’s law are taken into account. Instead of linearizing and developing the perturbation in monochromatic waves, it is proposed that the perturbation satisfy the Alfvén wave’s conditions. As a result, a solution is found that in the fully ionized limit, it coincides with Sallago and Platzeck solution for Alfvénwaves in Hall magnetohydrodynamics (doi:10.1029/2003JA009920 ). Furthermore, if electronic pressure and Hall terms are null, in the linearized limit, the damping is equal to the one described by De Pontieu, B. Martens, P. C. H. and Hudson, H. S. (DOI = 10.1086/322408), if one imposes that the plasma is a perfect conductor.
本文分析了在考虑电子压力、霍尔和欧姆定律的双极项的情况下，大振幅alfvsamn波在部分电离等离子体(PIP)中的传播。代替单色波中的线性化和展开扰动，提出了满足alfvsamn波条件的扰动。结果发现，在完全电离极限下，一个解与Hall磁流体动力学中alfv波浪的Sallago和Platzeck解一致(doi:10.1029/2003JA009920)。此外，如果电子压力和霍尔项为零，在线性化的极限下，阻尼等于De Pontieu, B. Martens, P. C. H. and Hudson, H. S. (DOI = 10.1086/322408)所描述的，假设等离子体是完美导体。
