A technique is presented for analyzing the effects of using various SNR models on the projected emitted X-ray spectra, which can be compared with observational data. It is assumed that the spatially integrated X-ray emission originates from collisions between ions and thermal electrons in an ionized plasma arising from gas through which a shock wave has passed. Only hydrodynamic SNR models are considered. Comparisons are made of curves of the Boltzmann-weighted ionization times and temperature as a function of the emission integral. Similar curves imply similar compositions and X-ray spectra. Elemental abundances vary linearly with their contribution to the integrated luminosity. A Sedov solution is shown to be a good approximation for SNR models of emissions produced by ionization close to a shock front. Finally, a similarity solution is demonstrated valid for approximating the spectra of a reverse shock into uniform density ejecta traveling toward a uniform medium.
