deuterium 氘，重氢
deuter-, 二，词源同two. 因这种物理元素其质量为氢的两倍而得名。比较tritium.

- In this scenario , hydrogen would no longer be stable , but its slightly heavier isotopes deuterium or tritium could be .
- 在这个设定中，氢不再是稳定的，但是其更重些的同位素氘和氚却是稳定的。
- A deuterium atom is the same as a hydrogen atom , except the former has an extra neutron in its nucleus .
- 氘原子和氢原子一模一样，除了其化学式的原子核中多了一个中子。

- nasa的远程紫外线分光镜（fuse）探测卫星已经探明尘埃团中氘的浓度，要比预期水平高很多。
- Shortly after his 14th birthday , taylor and brinsmead loaded deuterium fuel into the machine , brought up the power , and confirmed the presence of neutrons .
- 刚过完十四岁生日后不久，泰勒就和布林斯迈德为反应器注入了氘燃料，通上电源，并确认了中子的产生。
- Pure deuterium reactions also produce neutrons , though only about 1 / 3 of the fusion energy is released as such .
- 纯氘反应也会产生中子，虽然最多只能释放出三分之一的聚变能。
- Specifically , the ratio of heavy hydrogen , or deuterium , to regular hydrogen was too high in the comets .
- 具体而言，在彗星中，重氢，或者说是氘以及氢的含量更高。
- But there 's an answer : add a neutron to the single proton in the heart of every hydrogen atom and you have deuterium , also known as " heavy hydrogen . "
- 但有一个答案：添加一个中子到在每个氢原子的核心的单个质子你就得到了氘，也被称为“重氢”。
- Helium-3 has one less neutron than regular helium ( helium-4 ) and is also produced in the sun and almost as quickly consumed in fusion reactions as deuterium .
- 氦-3比普通氦（氦-4）少一个中子，并且同样在太阳里产生然后象氘一样在核聚变中迅速被消耗掉。

- 例如苯乙酮和氘苯乙酮气味分子具有相同的分子结构，其中一个是用称为重氢的氘原子构成。
- Pure deuterium can already be fused by technological means and was used in the first hydrogen bomb detonated in 1952 , but fusing it with tritium ( hydrogen with two neutrons , so it 's heavier than deuterium ) is even easier and this is the preferred reaction used by fusion research today .
- 纯氘已经可以通过技术手段被聚变，并在1952年首个氢弹引爆炸中使用，但是用它和氚发生聚变（氢带有两个中子，所以比氘重）甚至更容易并且这是当今研究聚变研究的首选核反应。
