The results obviously demonstrate wave diffraction in harbor on condition of boundary reflection. 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 order to decrease the reflection of wave on the boundary, spongy condition was used on top boundary.
为了减少波在边界上的反射，顶部边界采用了海绵边界条件。
In the radar wave migration processing, the boundary condition is usually considered as zero which is the cause of the interpretive precision depressed because of the reflection of non-media factor.
在雷达波偏移处理中。通常将边界条件设为零，但是这会在边界处产生由非介质因素引起的反射现象，使得剖面的解释精度降低。
Compared with the discretization scheme proposed earlier, the new one makes the reflection errors of PML absorbing boundary condition decrease by orders of magnitude when a larger time step is used.
和已有的离散方案比较，采用文中提出的离散方案可使理想匹配层吸收边界的反射误差成数量级地减小。
