A spark is produced by applying a high voltage (from approximately 6 KV to 40 KV) between the center electrode and ground.
火花由在中心电极和旁电极之间的高电压(大约6千伏到40千伏)产生。
2
The spark is more stronger when the central electrode is thiner. even at a relatively low voltage ignition phenomena also occur when the power concentrate at a plot.
中心电极越细所产生的火花越强、当电量集中与一点时，即使在相对较低的电压下也会发生点火现象。

The influence of laser sampling, auxiliary spark discharge voltage, and electrode point gap on analytical results was examined.
