Abstract

The present application discloses a method and device for measuring gas pulse discharge parameters, which are used to accurately measure gas discharge parameters under atmospheric pressure. The method uses a gas pulse discharge parameter measurement device to obtain the pulse voltage and loop current of the gas to be tested in the non-breakdown state and the breakdown state respectively; according to the particle control equation and the electric field control equation, a numerical simulation model is established; according to the numerical simulation The model and the preset equation system are used to adjust and optimize the stray capacitance parameter value of the numerical simulation model through the non-breakdown experimental data; according to the optimized numerical simulation model, the simulated loop current is obtained, and then the directional acceleration optimization method is adopted. , by calculating the standard deviation between the breakdown experimental data and the breakdown simulation data, the gas discharge parameters such as the Townsend ionization coefficient, electron adhesion coefficient, secondary electron emission coefficient and photoionization coefficient, etc., which take minimum values, are determined.
