论文摘要
这项工作致力于研究具有低分层的可压缩流体系统，该系统由快速的声波和内部波驱动。使用隔音模型的近似值是合理的。更确切地说，隔音模型捕获了非振荡的平均流和振荡的内波的动力学，而过滤了具有或没有初始声波的可压缩系统的快速声波。此外，研究了快速慢的振荡结构。
This work is devoted to investigating a compressible fluid system with low stratification, which is driven by fast acoustic waves and internal waves. The approximation using a soundproof model is justified. More precisely, the soundproof model captures the dynamics of both the non-oscillating mean flows and the oscillating internal waves, while filters out the fast acoustic waves, of the compressible system with or without initial acoustic waves. Moreover, the fast-slow oscillation structure is investigated.
