摘要
以近距星星表第兰版（CNS3）为样本，统计了太阳附近恒星的空间分布情况，结果发现在太阳附近恒星分布十分不均匀，许多地方密度极小，甚至为零，我们称其为空洞。本文给出了这些空洞的位置和大小，并提出它们可能与超新星爆发有关。
The spatial distributions of the stars in the solar neighborhood are presented based on 'The Third Catalogue of Nearby Stars'. It is noted that the distributions are severely inhomogeneous. The density is very small and even equals to zero in some regions, which we call voids. The positions and sizes of those voids are given. We suppose that these voids might be related to supernova explosion.
