Electrical stimulation was also used, although those in the sham group received lowervoltage and far shorter treatments.
电刺激在假针灸组也会使用，即使是很低的电压量和很短时间的疗程。

Step down transformers provide low voltage AC power for lighting, instruments and other circuits that use alternating current at a lowervoltage.
降压变压器低压AC电源提供照明，仪器仪表和其他使用交流电在一个较低的电压的电路。

An active and passive hybrid damping control manner with lowervoltage is proposed through both multiple piezoelectric patches and constrained damping layer for suppressing structural vibration.
