Abstract
Relations between radio surface brightness () and diameter () of supernova remnants (SNRs) are important in astronomy. In this paper, following the work Duric \& Seaquist (1986) at adiabatic phase, we carefully investigate shell-type supernova remnants at radiative phase, and obtain theoretical - relation at radiative phase of shell-type supernova remnants at 1 GHz. By using these theoretical - relations at adiabatic phase and radiative phase, we also roughly determine phases of some supernova remnant from observation data.
