Therefore, to minimize line imbalance, conductor transposition, as well as proper phase sequence and transposition orientation have to be used.
因此必须利用导线换位，并且采用适当的相序排列方式以及换位方向来减小线路的不平衡度。
By the feed-back control of the duty ratio according to the oscillations of the movable plate, the movable plate can be controlled to oscillate in the proper phase and at the proper oscillation Angle.
通过根据可移动板的振动对占空比的反馈控制，可控制可移动板以在适当的相位和适当的振动角振动。
