Limited roots and heavy fuel consumption meant that operating the Concorde was not good business.

有限的飞行路线和大量的燃料消耗意味着协和式飞机的运营并不划算。

The elevator car would climb the cable up and down without the need for all that heavy fuel.

电梯轿厢可以在缆绳上爬上爬下，而不需要那么重的燃料。

We actually use the fuel for the process. Their process is creating a heavy fuel oil that works for marine vessels.

我们实际上会用燃料来进行这个流程。这个流程会产生重油，用于海洋船舶。

Limited roots and heavy fuel consumption meant that operating the Concorde was not good business, however, it stopped flying in 2003.

不过，有限的飞行路线和大量的燃料消耗意味着协和式飞机的运营并不划算，它在 2003 年停飞了。

The United States and Europe react by creating zones where heavy fuel consumption is prohibited.

美国和欧洲对此作出反应， 设立禁止大量燃料消耗的区域。

A spacecraft would arrive at such high velocity it would need to haul a prohibitive amount of heavy fuel in order to slow down enough.

航天器将以极高的速度到达那里，它需要携带大量的重型燃料才能减速。

Come January, sulfur from heavy fuel oil will have to be a fraction of what it was for decades, setting off a scramble in the industry for solutions.

到明年1月，重油的含硫量将是数十年前的零头，这将使业内争先恐后地寻找解决方案。

Also, more vessels mean increased risks to Arctic ecosystems and wildlife, from heavy fuel oil spills to air and underwater noise pollution and the break-up of the remaining ice.

另外，更多的船只意味着北极生态系统和野生动物面临的风险增加，从重油泄漏到空气和水下噪音的污染，以及剩余冰层的断裂。

This could force the industry to abandon heavy fuel oil in favor of other hydrocarbons, which may push up its demand and price.

这可能会迫使该行业放弃重质燃料油， 转而使用其他碳氢化合物，这可能会推高其需求和价格。

Humans already do something similar by burning fossil fuels that contain sulphur, such as coal or the heavy fuel oil that powers big ships.

人类已经通过燃烧含有硫的化石燃料（例如煤炭或为大型船舶提供动力的重质燃油）来进行类似的事情。

Finally, the thick, high-sulfur residue is heated to above 450 degrees Celsius to form heavy fuel oil used by ships, and to obtain bitumen used for road construction and roofing.

最后， 将浓厚的高硫残渣加热到450摄氏度以上， 形成船舶使用的重质燃料油，并得到用于道路建设和屋顶的沥青。
