4. Compared with traditional motor, Halbach motor has higher air-gap flux density and lower rotor yoke flux density, which attributes to higher power density.
与径向电机相比，Halbach电机气隙磁密增大，转子轭部磁密减小，可有效提高电机的功率密度；
5. The driving current density plays an impelling effect on sheath ion energy flux. With the increasing driving current density, the ion energy flux increases.
驱动电流密度对鞘内离子能量通量起激励作用：随驱动电流密度增加，离子能量通量单调增加。
