The calculation of abundance of oxygen is conducted in atmospheres more than 300 stars of high luminosity, belongings to the galactic disk. Inclination of the radial distributing is got (O/H). Proofs are found that distributing can be more flat in external parts of disk. Distributing of abundance of oxygen is got in the disk of Galaxy. The statistical model of Galaxy is developed, a contribution is certain to the production of oxygen and iron from different galactic sources. Spectroscopy research of additional cepheid is conducted in South constellations in sending to the center of Galaxy, found out a plateau in distributing of chemical elements on galactocentric distances of 2-5 kps.
