Thus, the boundaryreflection effect and other effects must be considered during using the propagation-attenuation method to measure damping of a beam.
利用传播衰减法测量梁结构阻尼应考虑边界反射等影响。

The results obviously demonstrate wave diffraction in harbor on condition of boundaryreflection. Distribution of wave field in harbor is relatively appropriate.
结果比较清楚地反映出在考虑边界反射条件下波浪绕射情况，港内波浪场的分布比较合理。

In numerical wave simulation of finite difference for acoustic wave equation, due to the limitation of computer model, there inevitably exists strong artificial boundaryreflection.
