等离子体柱中的短波漂移旋涡

本文研宄等离子体柱中短波漂移非线性波。我们推导出柱坐标系中描述该波的非线性耦合方程组,求出一类不同于在笛卡尔坐标系中得到的偶极旋涡(vortex)的新解。这类新解由轴对称和反对称两部分组成,称之为径向旋涡。

SHORT-WAVELENGTH DRIFT VORTEX IN A MAGNETIZED PLASMA CYLINDER

In this paper,a system of coupled equations has been derived for nonlinear short-wavelength drift waves in a magnetized plasma cylinder.We have found a new solution of the system,which is different from the dipole vortex obtained in a plane geometry.This new solution,called radial vortex,consists of axially-symmetrical and antisymmetrical terms.In different limits,it reduces to the dipole vortex or the sole vortex.
