Abstract: Measurement of optical emission spectroscopy was taken to detect OH radicals  produced in the pulse discharge in air with unsaturated water vapor under atmospheric pressure. The analysis of the relative changes in optical emission spectroscopy indicates that: the number of OH radicals decreases while the diameter of the nozzle electrode increases; with the increase of humidity, the relative number of OH radicals first increases, then decreases，but increases again; the distribution of OH radicals in the discharge electric field gradually decreases from the center to the left, right and below, while it first increases and then decreases when it is upward.
