摘要
本文研究了在1993年3月28日之前发现的899颗超新星（SNe）的样本．其中277颗SNe被用来研究超新星在其母星系中的径向分布．我们研究了四个星系样本中超新星在产生单个超新星（称为一般超新星）的星系及在产生多个超新星（称为多重超新星）的星系中的径向分布．这四个星系样本为：总旋涡星系样本，Sb～SbC星系样本，SC星系样本，Sc～Sd星系样本．研究的结果表明：一多重超新星比一般超新星在其母星系中具有更集中于星系核心（大多数恒星形成发生的地方）的倾向。
We have compiled a sample of 899 SNe discovered up to March 28,1993, among which 277 SNe are used to study the radial distribution of SNe in their parent galaxies. The radial distribution of single SNe and multiple SNe in four galaxy samples, namely the total galaxy sample, the Sb-Sbc galaxy subsample, the Sc galaxy subsample and the Sc^Sd galaxy subsample are investigated. It is shown that there is a higher concentration of the multiple SNe to the center of their parent galaxies than the single SNe, implying that the star formation activities in the galaxies may affect the occurrence of the multiple SNe events which in turn affects the frequency distribution of SNe.
