Spectroscopy of H II Regions in the Late-Type Spiral Galaxy NGC 6946
  We present the results of spectroscopy of 39 H II regions in the spiral
galaxy NGC 6946. The spectral observations were carried out at the 6-m BTA
telescope of the SAO RAS with the SCORPIO focal reducer in the multi-slit mode
with the dispersion of 2.1A/px and spectral resolution of 10A. The absorption
estimates for 39 H II regions were obtained. Using the "strong line" method
(NS-calibration) we determined the electron temperature, and the abundances of
oxygen and nitrogen for 30 H II regions. The radial gradients of O/H and N/H
were constructed.
