Electron energy distribution functions for N2/O2/H2O/HCHO dielectric barrier discharge plasma were obtained by numerically solving the Boltzmann equation. The electron-molecule reaction constants were calculated using the computed electron energy distribution function. A space averaged chemical kinetics model in dielectric barrier discharge was reported. The evolution of·OH, HO2·and electron as functions of time were studied. The influences of H2O and O2 molar ratios on the generations of·OH and HO2·were also discussed. The calculated results were in od agreement with our experiments result.
