According to the spectral lines relative intensity of AC arc plasma in water

which was measured by spectral measurement system

the double-lines method is used to measure the electron excitation temperature.Under local thermal equilibrium(LTE) condition

the concentrations of electrons and the density of H

H+

O and O+ particles are abtained by Saha Equation method

and the concentration of plasma increases with the rising of arc power.This experiment can provide reference for the researching of AC and DC arc i...
