摘　　要：本文研究低β磁化热等离子体中非线性短波漂移阿尔芬波。我们导出了描述磁化等离子体中短波漂移阿尔芬波的非线性方程组,求出了该方程组的偶极涡旋解,这种解属于Rossby型涡旋,涡旋的势在离涡旋中心远处的渐近行为是按指数衰减的。In this paper, we have investigated the nonlinear short wavelength drift Alfvea waves in hot magnetized plasmas with low β(me/m1≤β≤1). The equation system which governs the dynamics of the nonlinear Alfven waves is derived and its dipole vortex solutions are obtained. These solutions belong to the one potential vortices or the Rossby type vortices. The asymtotical behavior of vortex potentials decays exponentially at distance far from the vortex centre
