查询词典 deuterium

It's between two isotopes of hydrogen, two kinds of hydrogen, deuterium, which is heavy hydrogen, which you can get from seawater, and tritium which is super-heavy hydrogen.

这两种氢，其一为氘，它是重氢，可由海水获得；而氚是超重的氢。

"Heavy water:Water composed of two atoms of deuterium (D; a heavy isotope of hydrogen) and one atom of oxygen, chemical formula D2O."

重水：由二个氘原子和一个氧原子组成的水，化学式为D2O。

"Heavy water:Water compose d of two atoms of deuterium (D; a heavy isotope of hydrogen) and one atom of oxygen, chemical formula D2O."

Deuterium, a natural isotope of heavy hydrogen, having one proton and on neutron, whereas normal hydrogen has one proton and zero neutrons, could be used routinely.

重水中的天然同位素氘具有一个质子一个中子，它不同于正常的氢只有一个质子没有中子，可以常规应用。

The neutrons are generated by bombard ing a heavy form of hydrogen, called tritium, with a lighter isotope of the gas, called deuterium. The resulting collisions create helium atoms and a stream of neutrons.

中子是通过氢的一种名叫氘的较氚轻的同位素来撞击它的一种名叫氚的重同位素而产生的，它们之间发生的碰撞创造了氦原子和中子流。
