这可能是因为月球形成过程中，撞击产生的热能使挥发性氢元素——水的重要组成成分——大量流失。
That could be because the collision that made the moon in the first place was so hot that volatile elements like hydrogen, a key component of H2O, largely burned away.
它们可能曾经几乎完全是由氢元素构成的，氢元素是热核融合的主要原料，正是这种反应让星星放出光芒。

有些是非常，典型的吸收线：，有些代表氢元素，有些代表钙元素，有些代表硅元素，有些代表镁元素等等。

研究人员利用所谓的离子显微镜来比较月球岩石中正常的氢元素含量及同位素氘的含量，元素氘比氢多带一个中子。
The researchers used what's called an ion microscope to compare the amount of normal hydrogen in the moon rocks to the amount of the hydrogen isotope deuterium, which carries an extra neutron.
重水因含重氢而得名。重氢是氢原子的一种，其原子核中含有一枚中子，加之正常氢元素中的质子，重量为一般氢原子的两倍。
Heavy water gets its name because it contains deuterium, a form of hydrogen that has a neutron in its nucleus as well as the usual proton and thus weighs twice as much as the ordinary sort.
当氢含量大于0.2%(质量分数)时，由于此时氢元素的固溶强化起主导作用，因此随氢含量的增加，峰值应力随之增加。
When hydrogen content was bigger than 0.2%, the peak stress increased with the increase of hydrogen content, because hydrogen played a main role of strengthening.
