By the ANSYS software this paper analyzes the electric magnetic field working in a magnetic suspension platform and gets the magnetic force line distribution map and the vectograph and isopleth of the magnetic flux density .

利用ANSYS分析软件，对这种新型磁悬浮平台进行了电磁场分析，得出了磁力线分布图、 磁通量密度 矢量 图及磁通量密度等值线。

The velocity vectograph and motion pattern of the flow in the hydrocyclone and the isoconcentration distribution diagram of the oil phase are calculated .

通过 数值计算得到了 液 - 液水力旋流器内流体流动的速度 矢量 图、 流线 图和油相及水相等浓度分布图。
