摘要：

We present new photoionization calculations for investigating gaseous regions that represent potentially expected stages of nuclear processing in the Crab Nebula supernova remnant. From comparison of the theoretical models with recent, extensive emission-line measurements, most of the emitting gas appears to be nitrogen-poor and carbon-rich. These results suggest that the precursor star had an initial mass greater than or similar to 9.5M(circle dot).
