正向波的英文

forward wave

• 正向:    forward direction
• 波:    wave
• 正向波形不稳:    positive creep

例句与用法

1. 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。
2. 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。
3. 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。
