Problems solved by technology

[0003] Since the arc is generated in a complex physical environment, there are many influencing conditions, and the research on the arc under a single condition cannot objectively and accurately describe the arc. The conditions for arc generation, such as different gaps, different electrode shapes, and different gas media , air pressure conditions, temperature conditions, flow velocity conditions, electromagnetic field conditions and other conditions, due to the mutual coupling of the conditions, the relationship is complicated, and a comprehensive and complete independent experiment and coupling experiment and analysis have not been done.
