In sparkle discharge ,following conclusions could be reached:(1) overall spectral intensity in nitrogen is lower than in oxygen . When water is added, integrality light intensity is lower compared with the pure gas condition.(2) No matter it is nitrogen or oxygen, when water is added, syllabify three spectral lines of atomic H: Hα(656.3nm), Hβ(486.1nm), Hγ(434.0nm) could be seen. What is more, when water is added into oxygen, the spectral line of H atom becomes stronger.(3) When discharge in pure nitrogen, the light intensity falls with the increasing gas flow rate. While if water is added, the light intensity will rises with the increasing gas flow rate.(4) When discharging in pure oxygen, the light intensity rises with increasing gas flow rate. While if water is added, with increasing gas flow rate the light intensity initially will change as this:first rise, then saturate at about 140l/h, finally falls.
