摘要：

Using two-color planar laser-induced fluorescence (PLIF) of OH hydroxyl radicals excited at two wavelengths and coherent anti-Stokes Raman scattering (CARS) spectroscopy of H2 molecules in a laboratory burner, we have measured spatial temperature distributions in the central section of a stationary atmospheric laminar flame of a methane-air mixture with partial preliminary mixing of the components. The results of a comparative analysis of the data on two-dimensional PLIF and point CARS thermometry of a spatially inhomogeneous flame are presented, and possibilities of complementary application of these methods for diagnostics are shown.
