| Description |
The analysis of different methods of determination of the abundance of oxygen in HII regions of the Galaxy have been derived. Recently offered P-method well coordinated with Te-method, and R23-method gives a big regular error. Oxygen abundances in HII regions of spiral galaxies have been derived through the P-method using published spectrophotometric data. The values of the radial oxygen abundance gradients were determined. The search for a global asymmetry in oxygen abundance distributions over the disks of galaxies was carried out. We do not find a significant signs of global asymmetry with one exception. Distribution of the abundance of oxygen in disks of the investigated galaxies are azimuthal-symmetric.
