不过蝙蝠侠确实配备了蝙蝠钩：带有特殊器件的挂钩可以扔到电力线路上，这样就可以给他们通信设备的电池充电。
But BATMAN does come equipped with a bat hook: a grappling hook that special operators can throw onto power lines in order to charge up their battery-powered communications equipment.
此时接上一条外线电路，电子便通过线路流动到p层。只要光束持续地撞击太阳能电池，就会有持续的电流。
An external circuit provides a path for the electrons to return to the p-type material, producing an electric current along the way that continues as long as light strikes the solar cell.
动态电压恢复器(DVR)对线路电压的跌落迅速作出响应，并通过储能装置(如蓄电池)恢复电压波形的失去部分。
A dynamic voltage restorer (DVR) instantly reacts to drop in line voltage and restores missing portion of waveform from an energy storage device (eg. battery).
