本文研究了二维物体在无限大、线性分层、非扩散粘性流体中作匀速运动时，大距离流动的一般性质。采用Oseen和Boussinesq近似对控制方程进行线性化，并将机身处的边界条件用线性化的动量积分方程代替。这个线性问题的解显示了上游的射流系统和物体下游的波的图案。粘性对这些背风波的影响被详细考虑。
The general nature of the flow at large distances from a two-dimensional body moving uniformly through an unbounded, linearly stratified, non-diffusive viscous fluid is considered. The governing equations are linearized using the Oseen and Boussinesq approximations, and the boundary conditions at the body are replaced by a linearized momentum-integral equation. The solution of this linear problem shows a system of jets upstream and a pattern of waves downstream of the body. The effects of viscosity on these lee waves are considered in detail.
