Introduction
Oil and gas pollutants on the soil surface can be detected by Laser withnon-contact and rapid method, but the detection signal is fuzzy and the detectionaccuracy is low under the solar radiation. The reason is that the detection signalis interfered by stray radiation produced by reflecting solar energy from the soilsurface and oil-gas interface. The photo-thermal transfer mechanism of laserdetection in oil and gas pollutants is scientific base to research how toeliminate the stray radiation, and the spectral properties of oil and gaspollutants and complex soil surface are key parameters to analyze thephoto-thermal transfer. Spectral properties of oil and gas pollutants and complexsoil surface are measured based on the combination of simulation and experimentalmethods at different temperatures. A model of phase change-radiation-convection coupled heat and mass transfer in the multi-phase medium of oil and gasis established by using a multi-methods. And then the infrared characteristics ofoil and gas pollutants on the soil surface were analyzed by comparative study, andthe interference factors and influence rules of solar radiation and groundconditions were determined. The interference in laser detection process wasanalyzed, and the high-precision detection method of laser was explored. The aimof this project is to understand the photo-thermal transfer mechanism of laserdetection of surface oil and gas pollutants, and to reveal the impact of all kindsof interference mechanism and rules, which provides theoretical basis forimproving accuracy and reliability of laser detection of the surface oil and gaspollutants. The research conclusion plays an important role in laser detection ofoil and gas pollutants.
