1、Analysis of causes as to why MCS propagates to the southwest of MCC indicates the propagation direction depends on the direction and velocity of the two convergences.
2、The upper and bottom sound filters may limit propagation direction of pressure surge, forcing it concentrated on the perforated interval.
3、The evolution equations of wavelength, phase velocity, propagation direction and amplitude of the AGW packet are derived.
4、The obtained polarization gratings are very useful for highly functionalized optical devices because they can control both the beam propagation direction and polarization state.
5、The results showed that the weak interface can block the motion of the dislocations and change the propagation direction of the main crack, and result in forming lamella fracture surface.
