在电磁搅拌作用下，电磁力的大小随钢液液池宽度的增加呈指数衰减趋势，其衰减速率与电流频率和搅拌器极距有关。
The electromagnetic force decays rapidly in the molten steel, and its decaying speed is related to the current frequency and polar pitch of the stirrer.
这两种衰减速率一致光组合成我们所看到的白光，为色稳定性的近紫外芯片激发的余辉二极管的制备提供了依据。
The same decay rate of two kind of light are verified to combine the white light uniformly, providing the possibility for fabricating long aftergolow WLED with color stability during decay.
波发生器由一对极的凸极式永磁转子构成，它是该减速器的快转子。
The wave generator is composed of a pair of protruding pole permanent magnet rotors. It is the quicker rotor of the reducer.
