| 摘 要： | 本文求解了二维不定常磁流体力学方程组,从而讨论星系磁场和星系激波的起源和演化过程。初始均匀的磁场将缠卷而在星系盘中形成螺旋形的结构,其中磁场和星际气体是冻结在一起的。分析了星际磁场对形成星系激波的影响。由于磁场不是很强,它对星系激波的影响不是非常强。 |

| Abstract: | In the present paper, the unsteady and two-dimensional magnetohydrodyna-mical equations are solved to describe the origin and evolution processes of the galactic magnetic field and galactic shock waves. The initial uniform magnetic field will wind into the spiral structures in the galactic disk, in which the magnetic field and the interstellar gas are frozen together. The influence cf the galactic magnetic field on the formation of the galactic shock wave is analyzed. As the magnetic field is not very strong, the influence is weak. |
