论文摘要
使用完全相对论的两流体流体动力学模型研究了磁化电子 - 符号（EP）血浆中纯粹固定大幅度电磁（EM）单独波的非线性传播，该模型构成了弱相对论$的物理状态，该模型构成了物理状态能量。在这里，$ p $是热压，$ n $数字密度，$ m $是粒子的质量，而$ c $是真空中的光速。文献中的先前理论[物理学。等离子体\ TextBf {11}，3078（2004）]通过电子和正面的相对论热运动提出并推广。虽然sub-alfv {é} nic和super-alfv {é} nic solitons在弱相对论制度中共存，但相反的超层流性EP等离子体仅支持sub-alfv {é} nic solitons。在这两个物理方案中，还检查了马赫数和孤子振幅的不同限制。
Nonlinear propagation of purely stationary large amplitude electromagnetic (EM) solitary waves in a magnetized electron-positron (EP) plasma is studied using a fully relativistic two-fluid hydrodynamic model which accounts for physical regimes of both weakly relativistic $(P\ll nmc^2)$ and ultrarelativistic $(P\gg nmc^2)$ random thermal energies. Here, $P$ is the thermal pressure, $n$ the number density and $m$ the mass of a particle, and $c$ is the speed of light in vacuum. Previous theory in the literature [Phys. Plasmas \textbf{11}, 3078 (2004)] is advanced and generalized by the relativistic thermal motion of both electrons and positrons. While both the sub-Alfv{é}nic and super-Alfv{é}nic solitons coexist in the weakly relativistic regime, the ultrarelativistic EP plasmas in contrast support only the sub-Alfv{é}nic solitons. Different limits of the Mach numbers and soliton amplitudes are also examined in these two physical regimes.
