计算结果表明，外加偶极子磁场使激波脱体距离增加，壁面摩擦系数和表面热流密度增大。

The results show that the shock standoff distance, skin friction coefficient and surface heat flux all increase with the strengthening of the external dipole magnetic field.

根据磁偶极子空间磁场分布，导出了在外部垂直方向弱磁场下管状工件表面细长缺陷产生的弱磁场法向分量的计算公式。

Based on the spatial distribution of magnetic dipole, the equation of the normal component of leakage magnetic field on the tube surface under low-intensity field was derived.
