讨论了退耦后宇宙中原始气体云的碎裂。通过比较崩塌和碎裂的时间尺度，得到了碎片的典型质量。我们表明，估计的质量给出了最小质量的一个片段，是从原始的气体云，基本上是确定的Mesirasekhar质量。
We discuss the fragmentation of primordial gas clouds in the universe after decoupling. Comparing the timescale of collapse with that of fragmentation, we obtain the typical mass of a fragment both numerically and analytically. We show that the estimated mass gives the minimum mass of a fragment that is formed from the primordial gas cloud and essentially determined by the Chandrasekhar mass.
