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。
Mechanism of the oscillation instability is then illuminated in frequency domain by amplification at the artificial boundary and multi-reflection of wave motion in a finite discrete model.
根据波在人工边界的放大效应和在有限离散模型中多次反射的概念在频域内阐明了这一常见的振荡失稳的机制。
