We supply power to the three nearby towns. 我们对附近的三个城镇提供电力。
Industry is a heavy user of electric power. 工业需耗费大量的电力。
The polarizer is aligned along one data stream of the pol-muxed RZ-DPSK channel and thus the RF power increases with the accumulated DGD, which can be used for monitoring. 调整偏振片的方向去对到偏振合并调制讯号中的一路偏振方向，然后所量到的电功率随著所累积的偏振色散增加，这个变化的趋势便可以使用来做监测的功能。
