The abundances of neutron-capture elements in metal-poor stars, tightly related to the star formation and evolution, provide important clues to the chemical evolution of the Galaxy.

贫金属星的中子俘获元素丰度与恒星的形成和演化密切相关，它为研究星系形成早期的历史背景和化学演化提供了重要信息。

By means of the component coefficient equation and the updated data of abundances of the solar system, we calculate the element abundances of 64 poor-metal stars.

利用分量系数公式并结合太阳系元素丰度的最新数据，计算了6 4颗贫金属星的中子俘获元素丰度。

But the fact that rocky planets can take shape around metal-poor stars means the first roughly Earth-like worlds may have formed long, long ago.
