A simple electronic circuit is adopted for compensating the power mains fluctuation.

采用了简便的电网波动补偿方案。

Such people power could provide an alternative to mains charging of electronic gadgets, reducing energy consumption and greenhouse gas emissions.

这样的人力能量能够提供电子设备充电所需的备用电源，降低能耗并减少温室气体排放。

The primary power supply is powered from the mains supply and energizes a lumped coil; the current ranges anywhere from 5 to125 amps.

主要的电力供给是来自市电电源并通过一个集合线圈激发；电流范围从5到125安培。

But it is a particularly good idea for an electric car because mains electricity can be used if the car is still plugged in, thus conserving battery power.

但对电动汽车来说这尤其是个好主意，因为如果车子仍然插在插头上，就可以使用市电，因而节省电池电力。

It is also experimenting with running cables from the mainland to its offshore platforms, to allow them to run off cleaner mains power, rather than small gas-fired generators.

同样，该公司在进行着试验——从陆地向离岸采油平台接通电缆，以允许他们使用更洁净的能源发电，而不是使用小型的天然气发电机。
