移相位

If the "0" and "1" to change the carrier phase, called phase shift keying.

如果&0&和&1&来改变载波的相位，则称为相移键控。

Its algorithm to recursively continue the source and receiver wavefields, which includes a wavenumber domain phase shift in a constant background medium followed by a phase correction in the space domain that accommodates lateral velocity variations, can tackle the effects of lateral velocity variations for imaging under complex overburdens.

其递归波场延拓算法包含波数域针对常速背景的相移处理和空间域针对横向速度扰动的相位校正，可以应对上覆地层速度横向变化对构造成像的影响。

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。

它是对输出时钟信号的相位噪声特性，杂散抑制特性等要求都很高的一种频率合成器，为基本信号生成模块到射频的搬移提供稳定的激励源。

They have many strange properties such as negative phase velocity, negative refractive index, perfect imaging, inverse Doppler effect and abnormal Cerenkov radiation.

负折射率介质最早由前苏联科学家Veselago在20世纪60年代从理论上提出来的，是一种具有介电常数ε和磁导率μ同时为负值的介质，它具有诸如负相位速度，负折射率，理想成像，逆Doppler频移及反常的Cerenkon辐射等多种奇异的物理现象。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
