hydrogen-air的意思|示意

Like other hydrogen cars, the Riversimple Urban car (RUC) is powered by a fuel cell that combines hydrogen with oxygen from the air to release energy and nothing more toxic than water.

和其他氢能源车一样，Riversimple Ur ban Car (RUC)采用燃料电池，电池将来自空气的氢和氧进行混合释放能量，除了水不排放任何有害物质。

The wide flammability range, 4% to 74% in air, and the small amount of energy required for ignition necessitate special handling to prevent the inadvertent mixing of hydrogen with air.

在空气中氢的易燃范围很宽，从4%到74%，而且点燃所需的能量很少，必须特别处理，以防止无意中把氢和空气混合在一起。

The cheapest option could be to use giant mid-air refuelling aircraft, such as the US air force's KC-10 Extender, filled with sulphur dioxide or hydrogen sulphide gas.

最便宜的方案是使用巨型空中加油飞机——例如美国空军的KC-10“补充者”空中加油机（KC-10 Extender），装满二氧化硫和硫化氢气体。

Sea spray – and, therefore, sea air – is full of negative hydrogen ions, charged particles that neutralise damaging free radicals (positive ions) and improve our ability to absorb oxygen.

大海溅起浪花，因而使海洋空气中富含负氢离子，抵消自由基（阳离子）带电粒子，增强我们的吸氧能力。

Since hydrogen gas is extremely combustible, when enough hydrogen gas is mixed with air, it reacts with oxygen. If there is enough hydrogen gas, it will react rapidly, producing an explosion.

因为氢气是高可燃气体，当足够多的氢气进入空气中，它就会跟其中的氧气反应。

Any purge method should be repeated as often as required to be certain a flammable mixture cannot be formed upon introducing hydrogen or air to the system.

任何净化方法都应该尽量多重复几次，直到确定在把氢或空气引入系统时不会形成可燃混合物为止。
