1·Perhaps the most fundamental is an abundance of elements that can be easily boiled out of hot rock.
也许最基本的一点就是水星大量拥有从沸腾岩浆中便可轻易获得的元素。
2·The rate at which massive stars form drops sharply as you venture outward from the Milky Way’s center, and the abundance of heavy elements falls with them.
你越往星系中心走，大质量恒星形成的难度就上升得越快，重元素的丰度也随之下降。
3·Metallicity is a measure of the relative abundance in a star of elements other than hydrogen and helium.
金属丰度是对恒星内除氢和氦之外元素的相对丰度的度量(天文学中比氦重的元素都叫金属。——译者注)。
4·"Stars in the center of the Milky Way are old and 'metal-rich' with a high abundance of heavy elements," Bobrowsky said.
银河中心的恒星都比较古老，富集金属元素，重元素的丰度很高。
5·With the crustal model and the petrochemical data, the average chemical composition and the abundance of major elements in Xinjiang crust are calculated and explored.
在地壳模型和岩石化学资料基础上，计算和研究了新疆地壳的平均化学成分和主要元素丰度。
6·Moreover, the turbulent stress also causes the convection the mixing action to strengthen, so elements abundance of the stellar interior and surface are all changed.
另外，湍流应力还使对流的混合作用加强，从而导致恒星内部及表面的各元素丰度都发生改变。
7·An INAA (Instrumental Neutron Activation Analysis) method was used to determine the abundance of rare-earth elements in 58 late Palaeozoic coals and related rocks in North China.
采用仪器中子活化分析法(INAA)测定了华北晚古生代石炭纪-二叠纪58个煤及煤层夹矸和顶底板样品的稀土元素含量。
8·The team's measurement of thorium revealed the overall abundance pattern of heavy elements for this object.
该队的测量发现钍的总体格局丰富的重元素，为这个目的。
9·There is an argument to express them in ground level abundance of the respective elements.
有理由把它们用相应元素的地平丰度来表示。
10·With the crustal model and the petrochemical data, the average chemical composition and the abundance of major elements in Xinjiang crust are calculated and...
在地壳模型和岩石化学资料基础上，计算和研究了新疆地壳的平均化学成分和主要元素丰度。
