Then the distribution of the magnetic forces in the maglev system was analyzed, and a set of formulas of the coupling was derived. 通過分析機構磁懸浮系統中電磁鐵的磁力分佈，給出了耦合磁力的計算公式。
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. 磁懸浮系統依靠列車上電磁鐵導向和鐵磁定子之間的吸力工作。
Plug up any cracks in the panel with plastic wood. 用塑化木材把板條上所有裂縫填塞起來。
The water gurgled as it ran down the plug hole. 水汨汨地從塞孔中流下去。
