Forged by the Milky Way's abundant stars, such heavy elements are the building blocks of terrestrial planets.───这些由银河系众多恒星锻造出的重元素正是类地行星的构建模块。
this group, most of those with traces of heavy elements also have traces of hydrogen.───这类白矮星中有着重元素痕迹者，大多也会有氢的痕迹。
These youngsters had low supplies of heavy elements-for example, their oxygen content was only 20 percent of the sun's.───这些年轻的恒星提供的重元素很少——例如，它们的含氧量仅为太阳的20%。
At least one earlier supernova must have provided the early star with its tiny percentage of heavy elements.───至少有一颗先前存在的超新星为这颗原恒星提供了极少量的重金属。
But most stars are not massive enough to create the pressures and heat necessary to burn heavy elements, so fusion and heat production stop.───不过大多数恒星都没有足够的质量以产生燃烧重元素所需的压力与热能，所以核聚变与热能产生过程都停止了。
But the new study shows that some nooks of the universe remained pristine long after stars had begun to spew heavy elements.───但是新研究表明在宇宙的一些角落在星体已经开始喷发重元素的很长一段时间之后依然保持着原始。
A large number of radioactive isotopes among the heavy elements are of three series.───重元素中的大量放射性同位素分别属于三个系列。
By means of SR X-ray fluorescence, we have studied the heavy elements in leaves for 8 species of plants in Zhongshan mine, Anhui province.───利用同步辐射X射线荧光分析技术，对安徽省钟山铁矿矿区的8种植物叶片内重元素进行了研究。
At the same time, the galaxy expels gas loaded with heavy elements into its halo and maybe even into intergalactic space.
In this paper a simple and feasible method of CNDO/2 parametrization for heavy elements is reported.
Stars congregate most tightly at the galaxy's center, so the life-giving heavy elements they create are most plentiful there.
The Dubna laboratory is one of the few in the world able to handle radioactive heavy elements such as californium .
But in the cold upper atmospheres of all four planets the heavy elements are almost perfectly condensed and precipitated out.
