查询词典 phase converter

Only oneA/D converter is needed to complete complex quadrature translation and digital downconversion, get in-phase component and quadrature component in digital field, and also,after intra-pulse compression is done, the signal-to-noise ratio is raised, and inter-pulsecompression is done in digital field, and finally, high range resolution profile is got.Two-step stretch processing method for MMW high-resolution RADAR is presented.

计算并优化了毫米波雷达中频信号带通采样的最佳采样频率，应用现有的集成电路技术实现对中频信号的直接采样、用一个A／D转换器在数字域完成复数正交变换，在数字域完成下变频、获得同相信号和正交相信号、完成对子脉冲的脉内压缩、完成对脉内压缩信号的第二次脉间压缩，从而获得高分辨一维距离像。

Based on the resonance reactor and the Magnetic Energy Recovery Switch , a novel single-phase AC-DC converter is designed.

将谐振电抗器和磁能恢复开关引入到单相AC-DC变换器中，设计了一种新颖的混合单相AC-DC变换器。

This article mainly introduces the advantage of synchronous multi-phase DC/DC converter in decreasing ripple current and increasing efficiency and gives result of simulation and practice.

像这样低电压和大电流的电源主要存在两个问题：①由于输出电压极低，很难提高电源效率；②由于负载电阻极低，若采用传统方式

To meet the requirement for the low-voltage and high-power output,direct-drive wind power generation system employed the topology which combines the dual-three phase permanent magnet synchronous generator and parallel converter technique.

为满足低压大功率输出的要求，直驱式风力发电系统采用双三相永磁同步发电机和变流器并联技术相结合的拓扑结构。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
