Description
Summary:	The new 3-stages method for the chemical composition and physical parameters of high-metallicity nebular objects determination was investigated. It's based on calculations of the optimization photoionization models (OPhMs) of these objects with using diagnostic rations between the emission line intensities. The sensitivity of the relative line intensities and the diagnostic rations to the chemical abundances variations was analyzed. It was concluded that there is necessity to include the He/H, O/H and S/H to the first stage of OPhMs free parameters.
