| Abstract: |
| A theoretical model of the plane sound wave reflecting and refracting on the parallel interface was founded. The expression of the reflection coefficient was deduced by the theoretical model. The variation law of the reflection coefficient versus entrance angle was discussed simply. The discussion about the reflection coefficient round the first critical angle and the second critical angle is conductive to the study of amplitude characters of sliding P-wave sliding S-wave and pseudo Rayleigh wave in the acoustic full wave. |
