1.【化】氢
1.a gas that has no color or smell and is lighter than air
1.Hydrogen and CO have both been used for estimation of noble metal surface areas.
夂？O都已用来测定贵金属的表面积。
2.The heat and light energy from the Sun is due to the fusion of hydrogen atoms at a very high temperature and pressure.
太阳的光能和热能是由于氢原子在极高的温度和压力下发生核聚变的缘故。
3.The gravimetric hydrogen production rate exceeds that of other solar-driven thermochemical processes by more than an order of magnitude.
而分解出氢的效率以重量计算可比其它太阳能热制程的效率高出一个数量级。
4.Most hydrogen fires will have the flame characteristic of a torch or jet and will originate at the point where the hydrogen is discharging.
大多数氢的火焰具有火炬或喷射器的特征，起源于氢泄漏点。
5.Hydrogen, a secondary energy carrier , can be converted to produce water and this water appears to be an endless source of energy.
二级能量载体氢可以被转换，产生水，这种水似乎会成为无穷无尽的能源。
6.It's designed for up to six people to live in, and is powered by an environmentally-friendly combination of solar power and hydrogen tanks.
它可以居住六人，由对环境友好的太阳能和氢气驱动。
7.The star used to be like the sun, a "main sequence" star that burns hydrogen by nuclear fusion, producing helium.
这颗恒星曾和太阳一样，是颗“主序星”（“mainsequence”）。它通过核聚变燃烧氢，从而产生氦。
8.That energy itself must be produced in ways that do not emit greenhouse gases for hydrogen to be a truly green fuel.
最理想绿色燃料则是按照一定的方式自己产生能量而且不会产生二氧化碳、甲烷等导致温室效应气体（如同氢气）。
9.The ships would turn wind power into hydrogen, which would be stored on board, to be unloaded later and used to generate electricity.
帆船把风力转换成氢贮存在船上，需要时卸载用于发电。
10.Still, these findings offer something of a conceptual shift in how to view human conditions where hydrogen peroxide plays a role.
对于如何看待过氧化氢在人体中的角色，这些发现仍然提供了概念上的转变。
