LAST December California approved a power line between San Diego and the Imperial valley-a spot blessed with sun, wind and geothermal energy resources.(去年12月份，加州批准修建帝王谷到圣地亚哥的一条输电线——帝王谷同时享有太阳能，风能和地热能资源。)
Secondly, power line noise channel and multi-path channel optimization modeling techniques based on artificial neural network are proposed.(其次，提出了电力线噪声信道和多径信道的神经网络优化建模方法。)
GE is promoting the smart grid with ads that show a scarecrow singing "If I only had a brain" from "The Wizard of Oz" while bouncing along an old power line.(通用电气公司正在推广智能电网，广告中有一个来自“绿野仙踪”的稻草人沿着一条旧电线蹦蹦跳跳并唱道“如果我有大脑”。)
He noticed the remains of a snake which was wound round the electric wires of a 16,000-volt power line.(他发现了缠绕在16,000伏高压线上的一条死蛇。)
That day, Margie told her a man had been electrocuted7 on a power line just two blocks from Bonnie's house.(那天队长玛吉告诉她说，就在离邦妮的房子两个街区远的输电线上有个人触电了。)
Save for two underwater connections to Long Island, new York State has not built a major new power line in 20 years.(二十年多来，除了两条连接长岛的线路外，纽约州还没有建设过其它新的大型输电线路。)
Therefore, auto power line layout and to science, otherwise will also cause additional loss of energy.(因此，汽车动力线布置也要科学，否则也会造成额外的能量损耗。)
Signal attenuation in the power line environment is often great, and unpredictable.(信号衰减在输电线环境经常是伟大和变化莫测的。)
It appears that they have finally succeeded in reconnecting a power line to one of the reactors, which will help pump much-needed cooling water.(看来他们终于成功了——将一条外部电源与其中一个机组的电力系统相连接，这将有助于输送所急需的冷却剂。)
Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth) ground.(请勿接触任何会为通向被测电路的共用侧或电源地的电流提供通路的物体。)
