本文考虑了任意气体的定常Oseen方程。Oseen算子的逆算子在一定的极限下通过跨音速一致地得到封闭形式。这个极限与从动力学理论推导出的纳维-斯托克斯方程的极限相同。得到了任意物体绕流的远场升力、阻力和能量耗散。作为另一个应用，显式地得到了超声速绕流半无限平板的流场。后一个问题作为基础的延伸Oseen理论，它给出了近似的皮肤摩擦任意机构。
The steady Oseen equations for an arbitrary gas are considered. The inverse of the Oseen operator is obtained in closed form uniformly through transonic speeds in a certain limit. This limit is the same as the limit under which the Navier‐Stokes equations are derivable from kinetic theory. The far field flow past an arbitrary body in terms of lift, drag, and energy dissipation of the body is obtained. As another application, the supersonic flow field past a semi‐infinite flat plate is explicity obtained. The latter problem serves as the basis for an extension of the Oseen theory which gives an approximation of skin friction for arbitrary bodies.
