    "abstract": "The system of hydrodynamic-type equations, derived by two-side distribution\nfunction for a stratified gas in gravity field is applied to a problem of\nultrasound. The theory is based on Gross-Jackson kinetic equation, which\nsolution is built by means of locally equilibrium distribution function with\ndifferent local parameters for molecules moving \"up\"and \"down\". The linearized\nversion of the obtained system is studied and compared with other results and\nexperiments at arbitrary Knudsen numbers. The problem of a generation by a\nmoving plane in a rarefied gas is explored. The WKB solutions for ultrasound in\na stratified medium are constructed in explicit form, evaluated and plotted.",
