本文研究了银河系中超新星的分布，并与超新星遗迹的分布进行了比较。色散测度被用作距离指示器，以获得恒星的光度、z距离和周期的分布。z距离分布在不确定性范围内与超新星遗迹的z距离分布相似。银河系中峰值光度≥ 1 fu（dm）2的恒星总数估计为5 × 105，误差为10倍。这些数据与假设一致，即超新星的形成速度与超新星的形成速度相同，如果假设超新星的时间尺度为107年。
This paper examines the distribution of pulsars in the Galaxy and compares it with the distribution of supernova remnants. The dispersion measure has been used as a distance indicator to obtain the distribution in luminosity, z-distance and period of the pulsars. The z-distance distribution is similar within the uncertainties to that of the supernova remnants. An estimate of the total number of pulsars in the Galaxy with a peak luminosity ≥ 1 fu(dm)2 gives 5 × 105 within a factor of 10. The data is consistent with the hypothesis that pulsars are formed at the same rate as supernovae, if the pulsars are assumed to have a timescale of 107yr.
