HALF-SPACE MOMENTS IN BOUNDARY PROBLEMS OF GASES KINETIC THEORY

The bracket integrals containing discontinuous functions of velocities for degree potential and rigid spheres potential are calculated. The solution of the temperature sliding of non-uniform heated gas near solid surface problem is obtained by using exact Boltzmann collision integral.

TRANSLATIONAL NONEQUILIBRIUM OF IODINE COMPONENT IN THE ACTIVE MEDIUM OF THE SUPERSONIC CHEMICAL OXIGEN-IODINE LASER

The model taking into account main physical processes, which take place in the active medium of the COIL, such as resonant radiation - iodine atom interaction, process of electronic energy transmission in the iodine atom - oxygen molecule collisions, elastic collisions of iodine atoms with buffer gas molecules - nitrogen is represented. The behaviour of excited and nonexcited iodine distribution functions in single-mode and two - mode generation regime is researched, the positions of modes and their intensities are defined.
