摘要：
Type Ib/c supernovae are shown to be concentrated to the inner edges of the spiral arms, with the distributions for type Ib and Ic supernovae being identical. We have found differences between the distributions of type II and Ib/c supernovae relative to spiral arms, suggesting that the type Ib/c presupernovae are, on average, younger.
