3 . a 5 - w millimeter - wave power - combining amplifier is implemented and fabricated . the compact bias circuits and power - protection circuits for mmics is designed 3 .研制了ka频段5w功率合成放大器,设计了紧凑的偏置电路和mmics功率单片的电源保护电路。
This thesis mainly expresses the design , research and analysis for millimeter - wave power combiner components and for the combining efficiency of power combiner system 本论文的工作主要是对毫米波功率合成相关组件及系统合成效率进行了设计、研究和分析。
The aim is to cut greenhouse - gas emissions by 2020 by at least a fifth , and more than double to 20 % the amount of energy produced from renewable source such as wind or wave power 计划的目的是:到2020年温室气体排放量减少到1 / 5 ,如风、潮汐等新能源20 %的利用率提高原来的两倍。
Those original targets were daunting enough : by 2020 the eu is supposed to cut greenhouse - gas emissions by at least a fifth , and more than double the amount of energy that is produced from renewable sources such as wind and wave power 新制定的宏伟目标包括:到2020年,欧盟将减少温室气体排放量的20 % ,同时可再生能源(如风能和水能)使用率要提高一倍。
Those original targets were daunting enough : by 2020 the eu is supposed to cut greenhouse - gas emissions by at least a fifth , and more than double the amount of energy that is produced from renewable sources such as wind and wave power 原来的目标就已经很难取得了:到2020年,欧盟要将温室气体排放减少至少20 % ,并将风能和波浪能等可再生能源的产量提高两倍多。
Wave energy is the transport of energy by ocean surface waves, and the capture of that energy to do useful work ? for example, electricity generation, water desalination, or the pumping of water (into reservoirs). Machinery able to exploit wave power is generally known as a wave energy converter (WEC).
