正向传播 meaning in Chinese
forward-propagating
Examples
- 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。 - This paper first introduced the pbd technique ' s basic principles and characters , these characters show that the pbd technique has many advantages in the nde ( non destructive evaluation ) field . then it described the theory model of pbd technique - three layers medium model , and explained the physical meaning of the model ' s solution
然后描述了光热偏转方法的理论模型- -三层介质模型，对三层介质模型的解的物理意义加以了说明，并着重论述了引起光热效应的物理量，即沿正向传播和反向传播的热波的物理意义。
