摘要：
The interaction of high velocity free-molecular gas flow with the solid surface is studied. The influence of the surface structure on the momentum and scattering indicatrix of reflected molecular flow are investigated. The results of theoretical and experimental investigation of the gas flow scattered by a rough surface are given. Data about the surface structure, received by atomic force microscope are also reported.
