2) According to the empirical formula X/(B-10) =20%, wherein: x is the dimension of the opposite side of the hexagon, B is the known tile width, 10 is the sum of the insulation safety distances at two ends, for example: the size of the ceramic chip is 150X 80mm, X =14mm can be obtained according to a formula, and when the ceramic chip is 150X 80mm, the thickness of the line needs to be designed to be 0.8mm, and the optimal concentration of the polygonal ozone with the opposite side size of 14mm is achieved.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
