Then the distribution of the magnetic forces in the maglev system was analyzed, and a set of formulas of the coupling was derived. 通过分析机构磁悬浮系统中电磁铁的磁力分布，给出了耦合磁力的计算公式。
The magnetic levitation system is based on the power of attracting between the electromagnets in the vehicle and the ferromagnetic stator packs in the guideway. 磁悬浮系统依靠列车上电磁铁导向和铁磁定子之间的吸力工作。
Plug up any cracks in the panel with plastic wood. 用塑化木材把板条上所有裂缝填塞起来。
The water gurgled as it ran down the plug hole. 水汨汨地从塞孔中流下去。
