  The 10^51 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
several supernova remnants have been found to be dominated by nonthermal
emission. Separating the thermal and nonthermal 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 designed to model spatially resolved 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 SN 1006, emphasizing the physical constraints that can be placed on SNRs,
abundances, and the cosmic-ray acceleration process.
