本文讨论了微耗散、微可压缩流体中的非线性重力内波，当介质的性质在由局部波结构决定的尺度上缓慢变化时，这种非线性重力内波的传播规律。双定时技术用于获得描述波包的振幅、相位和平均流的变化的输运方程。这些传输方程的各种解决方案进行了讨论，与相关的临界层吸收。
Nonlinear internal gravity waves in a slightly dissipative, slightly compressible fluid are discussed for the case when the properties of the medium vary slowly on a scale determined by the local wave structure. A two‐timing technique is used to obtain transport equations which describe the changes in amplitude, phase and mean flow of a wave packet. Various solutions of these transport equations are discussed, with relevance to critical layer absorption.
