heavy hydrogen

They detected a heavy hydrogen molecule called hydrogen deuteride .

他们探测出了一种叫做氘化氢的高质量氢分子。

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。

When the atoms of heavy hydrogen fuse in that plasma , neutrons are released that then hit the reactor wall , heating it .

当重原子氢和等离子体重合时，被释放出的中子会撞击反应堆外壁，并将其加热。

A nearly limitless primary energy source is the fusion of deuterium or heavy hydrogen ( one proton and one neutron ), which is found in the water of the earth .

几乎无限的一次能源是氘或重氢（一个质子，一个中子）的聚变，氘在地球的水中可找到。

Fusion power works by colliding heavy hydrogen atoms to form helium - releasing vast amounts of energy in the process , as occurs naturally in the centre of stars .

核聚变工程是通过重氢原子碰撞形成氦，反应过程中释放巨大能量，仿照恒星中心自然的反应过程。

The oxygen atom is nearly 16 times as heavy as the hydrogen atom .

氧原子的重量几乎是氢原子的16倍。

煤对重油非加氢改质过程的影响

The fuel will be made from two heavy forms of hydrogen , called deuterium and tritium .

燃料由氢的两种较重的同位素制造，分别称为氘和氚。

TLC determination of GROUP-COMPONENTS in heavy oils with hydrogen flame ioni-zation detection

薄层色谱-氢火焰离子检测分析重质油的族组成

This outflow contains both heavy elements and hydrogen , but in some regions the heavy elements are easier to see , and in other regions the hydrogen is easier to see .

此一喷出物同时包含重元素和氢，但在某些区域较易看到重元素，而在其他区域则较易看到氢。

The enrichment of heavy oxygen and hydrogen isotope in the solid phase , during the gas hydrate formation , causes a decrease gradient in the δ 18O and δ D profiles and indicates the gas hydrate existence .

氢同位素δD随深度略有下降（从11‰到-12‰），这与水合物形成时氢氧重同位素相对富集于固相有关，表明天然气水合物的存在。

However , the natural abundance of deuterium is very small , only about 0.015 % , so that how to separate deuterium from hydrogen is quite critical . The heavy isotope of hydrogen , deuterium , is an important material in nuclear industry .

然而在氢的天然同位素中，重氢含量只有0.015%，如何提取氢气中的氘气至关重要。

However , the values of porosity and permeability derived from NMR logging are lower than the real values because the heavy oil has lower hydrogen index and higher viscosity .

但由于稠油粘度大，含氢指数低，也造成核磁共振测井的孔隙度、渗透率偏低。
