If the detection information is the distance H between a person and the electrodes, the noise magnitude M of the electrodes, the ozone concentration N of the airflow flowing out of the electrodes and the air quality index X, and H₁≤H≤H₂、M₁≤M≤M₂、N₁≤N≤N₂、X₁≤X≤X₂Then the optimum inter-polar distance D of the electrodes_{Optimization of}＝D_{Best 1}+D_{Best 2}+D_{Best 3}+D_{Optimization of}4。

Therefore, in the technical scheme, if the detection information is different, the corresponding calculation method of the optimal inter-polar distance is also different.
