Lattice wave will be reflected when it reaches the boundary so that the reflectingboundary condition is more reasonable than cyclic boundary.
因为晶格振动的波在达到界面时会被反射，所以镜面反射边界条件与循环边界条件相比更符合晶格振动的特点。

This paper proposes a general model of sound scattering and directivity pattern for a vector sensor located on a complicated reflectingboundary.
利用边界元方法，在不规则障板边界条件下，对矢量传感器的散射声场进行了计算，得出了传感器的指向性图。

Marine sediment is the reflectingboundary of the shallow sea, and the sound wave in the wave-guide of the shallow sea is greatly influenced by the Marine sediment.
