dc.descriptionWe show the dependence of the Bayesian and the N2-derived oxygen abundances on the N-enrichment history of the star-forming galaxies. We select 531 metal-poor and ~20,000 metal-rich galaxies from the SDSS database for this study. Their "accurate" O/H abundances are obtained from Te and P-method, respectively. The discrepancies of the Bayesian and N2-derived abundances from these two "accurate" abundances show obvious correlations with log(N/O) abundance ratios.
