THE BASES OF SPECTRAL DIAGNOSTICS OF A GA S CONTAINING A CONDENSED DISPERSED PHASE

In the article the radiation of a gas containing macroscopic particles and an external light beam passing the medium are described. The Prob abilistic method of V.V. Sobolev used for solution of radiation transf er Equations, multiple scattering of light by particles is taken into account. The influence of scattered. particles on the radiation in spe ctral lines and continious spectrum is investigated theoretically and experimentally. The radiation in a closed isothermal volume containing gas and macroscopic particles is analyses. The relations for determin ation of gas and particles temperatures, concentrations of atoms by us ing the measured intensities are derived. Different experimental condi tions that differ by optical characteristics of particles and surfaces of object are described. The possibilities of the space distributions measurements when intensities are observed along a single line of sig ht are discussed.
