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，加州批準(zhǔn)修建帝王谷到圣地亞哥的一條輸電線——帝王谷同時享有太陽能，風(fēng)能和地?zé)崮苜Y源。)

Secondly, power line noise channel and multi-path channel optimization modeling techniques based on artificial neural network are proposed.(其次，提出了電力線噪聲信道和多徑信道的神經(jīng)網(wǎng)絡(luò)優(yōu)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.(通用電氣公司正在推廣智能電網(wǎng)，廣告中有一個來自“綠野仙蹤”的稻草人沿著一條舊電線蹦蹦跳跳并唱道“如果我有大腦”。)

He noticed the remains of a snake which was wound round the electric wires of a 16,000-volt power line.(他發(fā)現(xiàn)了纏繞在16,000伏高壓線上的一條死蛇。)

That day, Margie told her a man had been electrocuted7 on a power line just two blocks from Bonnie's house.(那天隊長瑪吉告訴她說，就在離邦妮的房子兩個街區(qū)遠(yuǎn)的輸電線上有個人觸電了。)

Save for two underwater connections to Long Island, new York State has not built a major new power line in 20 years.(二十年多來，除了兩條連接長島的線路外，紐約州還沒有建設(shè)過其它新的大型輸電線路。)

Therefore, auto power line layout and to science, otherwise will also cause additional loss of energy.(因此，汽車動力線布置也要科學(xué)，否則也會造成額外的能量損耗。)

Signal attenuation in the power line environment is often great, and unpredictable.(信號衰減在輸電線環(huán)境經(jīng)常是偉大和變化莫測的。)

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.(看來他們終于成功了——將一條外部電源與其中一個機(jī)組的電力系統(tǒng)相連接，這將有助于輸送所急需的冷卻劑。)

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.(請勿接觸任何會為通向被測電路的共用側(cè)或電源地的電流提供通路的物體。)
