为了比较陨石和太阳的成分，我们需要利用元素的比率，而不单单是原子的丰度。
To compare the compositions of a meteorite and the Sun, it is necessary that we use ratios of elements rather than simply the abundances of atoms.
生命若在太阳系其他地方引起相当的影响，那些对它们具有生死关键的相对化学元素丰度，无论是什么，很可能暴露它们的存在。
If life has had a comparable impact elsewhere in the solar system, the relative abundances of chemicals key for its survival -whatever they may be -could betray its presence.
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。
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.
