摘　　要：本文综合运用分子电流观点及磁荷观点,系统地计算了沿轴向、横向及其它任意方向均匀磁化的有限长永磁棒在轴线上的磁场以及无限长永磁棒在全空间的磁场.In this paper, the magnetic field distribution along the axis of a finite permanent magnetic cylinder uniformly magnetized in its axial, diametrical and arbitrary directions, and the magnetic field distribution in the whole space of an infinite permanent magnetic cylinder uniformly magnetized in its axial, diametrical and arbitrary directions have been systematically calculated in the view of molecular current and magnetic charge.
