The electron energy conversion processes were analyzed through calculating the established dielectric barrier discharge kinetic model

and the foundation was laid for grasping the mechanism of plasma assisted combustion.The results showed that the electron energy distribution function of dielectric barrier discharge plasma was mainly affected by the reduced field.With the change of the reduced field

electron energy loss in the proportion of different collisions types was different

and electron energy was primarily lost in the excited and dissociated collisions with N

moleculars with the commonly used reduced field which between 100 Td to 300 Td.For air and stoichiometric mixture of air and metha

about 50%and 126%of the discharge energy was used to heat the gas respectively after the discharge about 1ms.
