The 1051 ergs released in a supernova have far reaching consequences in the galaxy, determining elemental abundances, accelerating cosmic rays, and affecting the makeup of the interstellar medium. Recently the spectra of some supernova remnants have been found to be dominated by non-thermal emission. Separating the the thermal and non-thermal components is important not only for the understanding of cosmic-ray acceleration and shock microphysics properties but for accurate assessment of the temperatures and line strengths. New models in XSPEC 11 designed to model synchrotron X-rays from type Ia supernovae, can contribute to the understanding of both the thermal physics (dynamics, abundances) and nonthermal physics (shock acceleration, magnetic-field amplification) of supernova remnants. I will describe model fits to supernova remnant SN1006, emphasizing the physical constraints that can be placed on SNRs, abundances, and the cosmic-ray acceleration process.
