移相器

When applying phase-stepping interferometry to measure a surface, distortion will be caused as a result of various error factors especially the phase stepping error from the phase shifter. Even seriously flexuosity can be produced.

用相移干涉术测量物体表面形貌时，各种误差因素特别是相移器移相误差的影响使得表面形貌的测量偏离了实际值，甚至会产生形貌失真的现象。

According to this method,four different 11-step algorithms with four different window functions which are rectangular window,triangle window,hanning window,and blackman window are designed. Analysis and simulation show that hanning window and blackman window with small lobes are less sensitive to errors. Seven different algorithms with the same phase shifting interval π/2 are designed by hanning window function,whose phase shifting steps are separately 5,11,15,39,51,76 and 101 steps.

选择矩形窗、三角窗、hanning窗和blackman窗生成4种11步移相算法，对振动误差和相移误差的分析验证了旁瓣小的hanning窗和blackman窗生成的算法对误差的灵敏度要小；再选择hanning窗生成了移相间距为π/2的5，11，15，39，51，76和101步7种移相算法，仿真验证了步数越多主瓣越小，对振动抑制能力越好，但需要更高的微位移器移动精度来获得有效的干涉条纹。

The two-mode fiber acoustic-optic nonreciprocal phase shifter consists of twoacoustic-optic frequency shifters same in characteristic and mode strippers, etc. Socharacteristic of the acoustic-optic frequency shifter and the identification of twoacoustic-optic frequency shifters' characteristics are very important.

双模光纤声光非互易相移器由两个性能一致的声光移频器及模式剥离器等构成，因此声光移频器本身的性能如何以及两个声光移频器的性能是否一致非常关键。

TMI Digital or Analog phase shifters are of two basic design.

我公司的数字或模拟移相器有两种基本设计。

The phase shifters (0),(1),(2),(3) control the elevation position of the beam.

Then the Ka band distributed MEMS phase shifters are designed and manufactured using proper process.

在此基础上，设计了Ka波段分布式MEMS移相器的版图，采用适当的工艺进行实际制备。

Therefore, low loss and low cost microwave phase shifters are required to improve performance and reduce the cost of phase arrays to ensure widespread application.

因此，低损耗，低成本的微波移相器起到了改善相控阵的性能，降低其成本的重要作用，这样相控阵才能得以广泛使用。

The key for phased array antennas with good functions is the use of controllable phase shifters.

其中可控数字移相器的使用，是相控阵天线优越性能实现的关键，但由此引入的相位量化误差，严重影响了相控阵天线的波束指向精度。

These phasers are adjustable over the range 0 to + 2 radians.

移相器可以在0到+2（译者：+2π？）弧度之间调整。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
