摘要：
We registered axial profiles of electron temperature, plasma potential and concentration of the direct current glow discharge in nitrogen at different gas pressure and discharge current values. We observed that in a broad range of experimental conditions the plasma concentration experiences 15. . .16 times decrease along the negative glow length. Maximum values of plasma concentration and electron temperature are registered at the cathode end of the negative glow, and the electric field strength is small. On leaving the cathode the plasma concentration and electron temperature in the negative glow are decreasing, here a region with a negative field may also form.
