direction propagation的意思|示意

The obtained polarization gratings are very useful in fabricating highly functionalized optical devices because they can control both the beam propagation direction and polarization state.

记录得到的偏振光栅可以控制光束的传播方向和偏振态，在功能性光学器件中有很大应用价值。

Therefore, GBRS have a useful selective effect with respect to the frequency and propagation direction of relic HFGWs.

因此，高斯束谐振系统对高频遗迹引力波的频率和传播方向具有良好的选择效应。

This method can effectively determine the direction of the pressure wave propagation and source, thereby excluding the impact of adjustment of working conditions, reduce the system false alarm rate.

该方法能够有效的判断压力波的传播方向和来源，从而排除了工况调整的影响，降低了系统误报率。

The approach takes into account not only the effect of direction of seismic wave propagation but also the effect of deformation of the foundation rock through which the waves pass.

该法不仅考虑到地震波传播方向，而且还考虑到坝基基岩变形对堤坝动力反应的影响。

The dispersion is due to the inhomogeneity of medium, which will lead the energy of sound to deviate from its direction of propagation.

另一部分则是由于声波在不均匀介质中的声散射把能量散射到其他方向，而使原来传播方向上的声波能量减弱。

The evolution equations of wavelength, phase velocity, propagation direction and amplitude of the AGW packet are derived.
