    We propose a systematic study of the supernova remnants (SNRs) in the
    LargeMagellanic Cloud (LMC).  The broadband spectral data from ASCA
    will be analyzed in the context of a nonequilibrium ionization model
    which allows determination of mean plasma temperatures, ionization
    time scales,and elemental abundances. With these results for the
    sample we will be able to (1) determine whether or not rapid equilibr
    ation of electron and ion temperatures occurs at the shock fronts of
    SNRs, (2) find and study young,ejecta-dominated remnants, and (3) det
    ermine the elemental abundances in the LMC.
