Recently, the research of the dependence of ion movement on ion diffusion and carrier gasvelocity distribution in high strength electric field has achieved preliminary results.
The research results showed that the boosted wind speed or the velocity of gas leakage accelerated the gas diffusion, and the diffused gas concentration to the leeward side was decreased.
