它是以这种电压馈入电力网。

It is fed into the grid at this voltage.

然而，水平参差不一的电力网还存有问题。

And then there is the question of the creaking grid.

Bertram博士希望在后几年里，电力网供电的OLEDs会商业化起来。

Dr Bertram is hopeful that mains-powered OLEDs will be commercialised in the next few years.

最近几年，电力网供电的CFLs和LEDs的出现开始将他们转变成白炽灯的直属插件替代品。

In recent years the emergence of mains-powered CFLs and LEDs has started to turn them into direct plug-in replacements for incandescent bulbs.

高空核电磁脉冲(HEMP)能使通信系统失效，甚至能使距爆炸地点十分遥远的电力网失效。

HEMP can disable communications systems and even power grids at enormous distances from the burst.
