查询词典 prepositive

There are three parts included. The first part is the prepositive-amplifier, it gets broadband high gain and flat frequency response. The second part is the U band quadrupler, which composed of two doublers using a PHEMT chip HMMC-5040, a Schottky diode of DMK-2790, a HMMC-5040 amplifier, and a fin-line transitional stage. Maximum output power higher than 60mW is obtained in V band. The third part is a 2nd harmonic gunn oscillator injection locked by the Fundamental Wave,which get about 2GHz locked bandwidth in W band.

电路主要由三部分组成，第一部分为采用HMMC-5618设计的前置放大器，实现了宽带高增益和平坦的频率响应；第二部分为设计的主体，由HMMC-5040设计的二倍频器、DMK-2790设计的二倍频器、HMMC-5040设计的放大器及鳍线过渡段组成的U波段四倍频器，在U波段实现了最高60mW以上的输出功率；第三部分为基波注入锁定谐波Gunn振荡器，在W波段实现了近2GHz锁定带宽。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
