正向波 meaning in English
forward wave
Examples
- Instantaneous propagation of the voltage sum of forward wave and backward wave , namely the standing wave , is not standing still except in case of total reflection
传输线上瞬时弦波电压等速传播之正向波与反向波合成之驻波，除非是全反射，并非如其名称停驻不前。 - The variation of db magnitude attenuation and phase delay of reflection is uniformly proportional to distance along the line toward the direction of reflection , where the phase delay is 360 degree per wave length , the db attenuation per meter is twice the one way db attenuation per meter of forward or backward wave
沿传输线之反射，即反向传播与正向传播电压沿传输线之相量比，其相位落后及分贝衰减沿反射方向之变化则正比于线长，相位落后为每半波长三百六十度，每米之分贝衰减为正向波或反向波单程每米之分贝衰减之两倍。 - In order to control the polarization characteristics , the phase retardance mirror must be used . additionally , in order to suppress the reverse wave in ring resonator , the phase retardance mirror must also be used to preserve the polarization characteristics of the reflected reverse wave by suppressor . the conventional film stack ca n ' t satisfy the high power coil development requirement
另外，通过对高功率coil用环行非稳腔内倒向波抑制的分析表明，为实现倒向波的抑制，倒向波被反馈到腔内正向波中的部分必须保持偏振状态不变，否则，起不到倒向波抑制的作用，这也需要用到高反射位相延迟镜。
