Ⅳ. 段落翻译 ⑴变压器的初级绕组是馈有交变电流的线圈，而次级绕 组是通过变化的磁通传给有功率的线圈。初级和次级 的名称只取决于变压器连接的方式；任一个绕组均可 是初级，于是另一个就是次级了。 译文：The primary winding of a transformer is the coil which is fed with an alternating current, and [或： while] the secondary winding is the coil to which power is transferred via the changing flux. The designations of the primary and the secondary depends only on how the transformer is connected; either winding may be the primary, and the other is then the secondary.
