论文摘要
我们研究假设热区域中原始密度不均匀性可能形成的原始核合成。结果表明，到目前为止，各个地区都获得了异常高的金属性。该结论在此类区域的广泛初始参数中。我们考虑了这些区域内的热核反应速率和估计的氘3和-4的丰富性。已经确定所有重子都倾向于形成氦4，这是较重元素形成链中的热核连接。
We study primordial nucleosynthesis in hypothetical hot regions that could be formed by the primordial density inhomogeneities. It is shown that the regions survived up to the present times acquire an abnormally high metallicity. This conclusion holds in wide range of initial parameters of such regions. We considered the thermonuclear reaction rates and estimated abundances of deuterium and helium-3 and -4 inside these areas. It has been established that all baryons tend to form helium-4, which is the thermonuclear link in the chain of formation of heavier elements.
