3D Model: Model A Cylindrical Arc Chamber With Transparent Walls To Visualize Internal Structures. At The Base, Place A Pointed Cathode And Above It A Hemispherical Anode. Include A "field-guiding Structure" Composed Of Ring Electrodes That Increase In Density From Bottom To Top To Represent The Early-stage Electric Field Enhancement. Mid-chamber, Add A Moving Seal Piston System Driven By Gas Pressure, Visually Linked To A Simulated Airflow Input Port On The Side. At The Top, Insert Porous Radial Grid Plates ("孔状栅片侧板") Aligned Parallel To Airflow To Represent Late-stage Arc Suppression. Add Animated Arrows Showing Electric Field Lines And Airflow Paths Guiding The Arc Upward And Extinguishing It.
